Saturday is National Trails Day, as determined by the American Hiking Society, which appears to be a society of hikers in America. Now that we've finally shaken off the brrr of our 50-degree winter, it's time to get out and enjoy the triple digits with a nice walk. A saunter. Maybe even a stroll. Or, in a nod to the early voting now going on, a constitutional. Point is, get out there! Here, from our March issue, is Desert Companion's guide to some fine local urban and suburban trails. Remember: Be sure to take plenty of water — because I'll probably forget mine and need to borrow some.
