“Well, which one, dammit!?” I snarl at the GPS when it tells me to take the left exit and the traffic demands a quick and irrevocable decision. (Yep – on a long, solo road trip it is perfectly normal to have conversations with your GPS!) After weeks of dawdling on back roads, the downtown St. Louis rush hour traffic is hitting my nervous system like a splash of cold water in the face! Thankfully, the little machine isn’t programmed to get in a snit in the face of my bad behavior and she continues patiently directing me to my hotel.
