Day 28, 29 - Tucson, AZ and Biosphere 2
Sunday (28) - Another hot day at 90°F by mid-afternoon. The two A/C units did a passable job. There is still a lot of heat that gets into the RV as the insulation isn't that great. And without a lot of wind, I could have the awning out to shade the refrigerator. It's been doing good with freezer temperatures around 3°F if I don't have the ice maker running. The additional load of making ice will raise the temperature by about 10°F.
Monday (29) - Today, we visited the Biosphere 2 site being operated by the University of Arizona. It is located about twenty miles north of Tucson. The purpose of the experiment was to replicate the biological processes on earth and see if humans can survive. They grew all their own food and had no physical supplies except what they brought in with them when the experiment started.This is the residential complex and the dome on top is the library. Apparently, it wasn't used much due to the long spiral staircase but from the pictures, the 360° view was pretty good. The glass pyramid structures are the different areas such as desert, rainforest, ocean, etc. They are full of vegetation all nicely labeled with the species and what part of the planet they were from.Saturday, April 10, 2021

Day 22, 23, 24 - Benson, AZ - TT
Monday (22) - This morning, we headed back into Tucson for a birthday party. Bridget ordered a cake from Safeway and, I believe, she is picking up some pizza somewhere in Tucson.
Tuesday (23) - A test session this morning and another this afternoon. I began to pack up stuff in preparation for leaving here tomorrow. I figured that this afternoon was going to be a bit too hot to sit outside so the table, chairs, and outdoor “rug” are now packed.
The 5amp AC fuse on the refrigerator control board blew for the third time in 19 months. It just switches to propane when it blows so not a serious problem. I think it has something to do with direct sun on the outside wall and not enough airflow to keep the temperature down. Just a hunch…
Wednesday (24) - A short travel day today. Only 44 miles to the KOA in Tucson, AZ. We needed to be “out” of the Encore system for seven days. We will be returning here in Benson next week. There are other parks in Mesa and Casa Grande but we like this place.
