My site at Justin's Diamond J RV Park borders directly to the desert. This area is part of the protected Tucson Mountain Park. There is also a complete trail system called "The Cederlund Trail System". That is where I spent a couple of hours today hiking along some of these trails. There are all kind of cacti in this beautiful Sonora desert.

For dinner they had a guy coming in and make pizza all you can eat for $5 - pretty good price and the pizzas were excellent.
