Saguaro National Park
After getting back from Kitt Peak, I spent weekend in Tucson exploring the desert. The first day I went to Saguaro National Park, which contains one of the densest populations of the "classic" cactus - the Saguaro. It wasn't the most amazing park I've ever been to, but the Saguaros were definitely interest, and the landscape is definitely different (even compared to Joshua Tree). But, the cacti were definitely fascinating.
