I'm not breaking my shoe rule, but I'd hoped to only take the pair that are on my feet. Yes, I have a shoe rule for traveling - a maxium of two pairs of shoes go with me on my trips. The first pair is dictated by my planned activity. I'm planning to hike in Sedona, so hiking showes are on my feet. And my hiking shoes are so comfortable that I thought I could get away with a single pair of shoes for this quick escape.
Oh, but wait - look at that weather forecast. Mixed precipitation. It still says mixed precipitation... Well, if I'm going to be tromping around in the rain (or snow?), I guess I'd better take another pair of shoes so I can have dry feet in the evening. OK, 2 pairs, that's still within the constraints of the shoe rule!
