It worked! I stopped at the Patagonia post office, walked in and said I had a General Delivery package waiting, and she recognized me name! So I now have four new pairs of shorts that are Bermuda length. Yea.
This part of Arizona is part of the Chihuahuan Desert ecosystem, not the Sonoran Desert, so no big-armed cactus. It is almost 4,000 feet high, however, and a lot dryer, so interesting. There are large, flat areas surrounded by craggy mountains. http://www.desertusa.com/chihuahuan-desert.html
The lake and campground are only about 12 miles from the Mexican border, but I only saw a couple of border control trucks and a patrolling helicopter once in a while.
This is an older state park, so sites were small and closer together than I like, but there were some very friendly people. The couple next door offered any help I needed once they heard me cough I couple of times.
Hard to see the lake, but it is behind all the mesquite trees.
Since my cough was not going away and I was having problems sleeping, I made a visit to another urgent care center in Green Valley, AZ, about 50 miles north. The physician's assistant I saw gave me advice on all the over-the-counter medication I was taking and a prescription for codeine cough syrup, which made it a lot easier to sleep.
So, I am back posting, albeit still not feeling 100% well. I made another grocery run, and was supposed to be do laundry, but was still too shaky and weak, so skipped it. I will be driving to Tucson tomorrow, and hopefully can get laundry done on the way.
