So, as we left Catalina State Park, we decided to go to Biosphere 2 nearby.

Very cool. Inside were living quarters, gardens (fruit trees, vegetables and animals), an ocean, a desert, and a rain forest.

Rainforest

700,000 gallon "ocean"

Desert

In the early '90s, eight people lived inside this completely sealed environment for 2 years, growing their own food, getting oxygen from plants, and maintaining all of the equipment. Their only outside contact was through television, phones and the internet. It is now owned by the University of Arizona, which does all kinds of scientific research in conjunction with scientists all over the world.



Some of the current projects are assessing effectiveness of different types of solar panels, assessing the effect of different amounts of rainfall on the rain forest, and changing CO2 levels in the ocean to see the effects (the coral reef has already died).







After leaving the biosphere we had to return to Larry's to pick up our hiking pack with our water bottles in it. This set us back about 1 1/2 hours so we only made it to Gila Bend where the only option was a KOA. At least it had a laundry, so we got caught up on that. It's not all glamour living on the road!

Our next stop was the Painted Rock Petroglyph Site. Not a very big site but interesting. Some of the petroglyphs were done BC!

They were prolific!

The grid was supposedly done BC.

We headed on toward Yuma, which is a big city when the snowbirds are in town. We stayed in a 55+ RV resort. When checking in the desk clerk told me that the town population grows by 80,000 in the winter! We noticed that most of the license plates were from Canada and, of course, the northern US. Nice place for a night, but way too many people for us. However, the bar and restaurant on site were nice. 😃

We finally crossed into California today! But first, we saw where all of our fresh food comes from. The fields along I-8 are enormous. We saw seas of cabbage, followed by kale and lettuce. Any fresh vegetable that you find in the store was being grown there. It was amazing! We were moving too fast to take pictures, though.

We are now in a San Diego county park that is just a few miles from Tecate, Mexico. We can see Mexico from our site. 😁 We saw miles and miles of border wall between Yuma and our park.





The park is nearly deserted except for a few other campers and the hawks and vultures!

Temperatures have been fabulous the last couple of days, and last night was the first night we didn't need heat, followed by today being our first day in shorts. Woo-hoo!

We did not exceed our limit! 😜

We moved on from Kartchner Caverns, where we have stayed before, to a county park, Gilbert Ray, adjacent to Saguaro National Park West. One of a couple of great recommendations by our friend Merry! While out on a short hike through the desert, we came upon Old Tuscon Studio where hundreds of movies have been filmed. It is mainly a tourist site now but occasional movies are still filmed there. We had a fun afternoon there, which included watching a condensed re-creation of The Hanging.

The next day we hiked up Brown Mountain in the national park. After walking back and forth to the trailhead several times (dead camera battery, forgot the phone, etc) we finally started on our hike.

We reached the peak?

We thought we reached the peak but when we went around the next curve, found another higher peak! Onward and upward!

The Saguaro cacti are everywhere! I learned that they only grow an inch in the first 10 years, and don't grow their first arm until they are around 100 years old! The ones with multiple arms are between 100-200 years old!

Out of control

And that's why it's called Saguaro National Park! They're everywhere!

They are majestic even in death.

 

Next, we moved on to Tuscon where we spent the day hiking with an old friend, Larry. If you ever get to Tucson, don't miss Sabino Canyon. It's beautiful and right in the city. We had a lovely dinner and breakfast with Larry before we had to move on. But not before taking advantage of a real shower in his house. 😉

We got a late start so didn't quite make it to the peak, but we have to leave something for next time!

It's always sad to leave but California is calling.

Denny crossing the creek

But first, Catalina State Park, another delightful recommendation by our friend Merry. Due to poor planning, we could only get one night. However, with so many lovely hikes and geocaches left to do, we will have to go back!

There were many creek crossings. Thank goodness for strategically placed stepping stones!

Leaving Cedar

So we have been on the road for a week and are finally staying in a campsite for more than one night. We had planned to stay a couple of nights in Hot Springs National Park, but the government shutdown changed that. The Buckstaff bath was open, though, as it is run by a private company. I was so happy to get my annual mineral bath spa treatment! However, the museum that Denny likes to peruse while I am in there was closed. I sure hope the shutdown ends before we get to some planned national park stays in California!
From then onward, every night when we watched the news, there was a cold front on its way. So in the morning we would pack up and head further south. We are now a little south of Tucson and...a cold front moved in overnight! We're still going to go hiking today and spend the next 5 days enjoying this beautiful area. We probably won't have as much company hiking since the high temperature will only be 56, but as hardy-ish northern Michiganders we will be fine, especially since it's also going to be sunny!
Our new motor home is working out great! We love the extra living space and the king bed! Still trying to get the cupboards arranged, though. It's a work in progress.
We have the cat (Kismet) with us again. I know, we thought she was going to die on our trip last year. She has been very ill a couple of times but continues to do well in spite of her kidney disease. She's taken to traveling again and after the first two nights (when she meowed all night) has adjusted well.  She complains when I put on her harness but doesn't seem to mind going outdoors except when it's windy.

We stayed at Monahans Sandhills State Park in west Texas; I guess it's their version of sand dunes. Nice but much smaller. When we got to the top of a dune, I kept expecting to see water, but no matter how high we climbed or how far we walked, all we saw was more sand!

Meanwhile, on the home front, Rochelle is dealing with having a new furnace put in, some sort of water pipe leakage making the drive an ice rink and sub-freezing temperatures. I wish we were there to help!
