In the Phoenix area there is a 42 mile loop trail that circles the valley. The Maricopa Trail. There are several trailheads around the loop and the Agua Fria trailhead is out near Lake Pleasant. Mike and I did a few miles on this portion of the trail.
Our wild critters of the day were burros. We came face to face with the male (called a "jack") almost as soon as we hit the trail. As you can see, he has been in a few fights. Later on we spotted the small herd made up of 3 females and 2 little ones. We spotted a couple more up on a ridge. Very cool!
