After flying to Charlotte, sitting in a windowless conference room for hours, then going out for drinks, I was feeling like jiggling blob in dire need of some movement. Any movement. My resolve to rest was not helped by the fact that Charlotte was having a few days of very mild weather. When we finally exited the conference room last night, it was in the sixties. When I checked my phone on waking, it was still just a few ticks below 50 degrees. How could I pass that up?
