I knew the Coronado National Forest was full of them. I just didn't know they looked like cartoons. Here they are. Thousands of them. For miles. Walk this whole 16-mile trail outside Tucson, Arizona. 5 or 6 great hours. More than 2,000 calories burned. The temperature: in the high 60s F. About the same as Phoenix, 100 miles away. A little too warm for football. Ya think?
