I spent the winter in Tucson. While it was a little more rainy than I've experienced here in the past, the weather was pretty nice. While the rest of the country suffered through snow and cold weather, I suffered through sunny skies and temps in the 70s.
Places that I visited while here include Saguaro National Park, Sabino Canyon National Recreation Area, Gates Pass (in Tucson Mountain State Park), and the San Xavier Mission. Below are photos from these places.
