It looks like rain, so I head for a non-canyon hike. The trails in Saguaro National Park are so nice for barefooting, I make the whole run shoeless. Along the way I pick a spot and take a waypoint for Ann to find when she follows – our own simple geocaching game. The lime falls trail is a little sharp, but worth slowing down to look at the strange rock pools. On my way back the rain begins, and the ensuing smell that rises from the wet desert ground is intoxicating. Just as I’m beginning to tire, my longest barefoot run so far is over.
