I have running routes in many of my favorite cities, none more treasured than this one in Tucson. From Simon and David’s house, down through the neighborhoods (where everyone seems to have at least one barking dog; I only know the hyperactive chihuahua Muchachito by name), along Congress Street and onto the path that follows this dried-up river bed. Then it’s out through desert landscape to the prison and back, about five miles total. But all of it is flat. And warm. A nice treat to run in shorts and a T-shirt mornings in early March. And while my wildlife sightings are usually limited to other runners, cyclists and the occasional prison work crew, I’ve often see quail, prairie dogs and rabbits, even some cartoon-like roadrunners and coyotes along the way. I start out along the A Mountain side (see it there on the right?) and cross the river for my return, passing behind Mexican-American homes with chickens and horses. And, of course, more dogs. And because the air is so dry, you do break a sweat, but it evaporates almost instantly.
