I had 30 minutes and wanted to make the most of them. And it wasn't actually raining (as it is now). What else to do but walk as fast as I could without running, stoke the human engine? Pull my hands into my sleeves, cinch the belt as tight as possible... and go.
Traffic lights work against this process, since it's all about momentum. But once I was on the Capitol grounds I was warmed up within minutes.
The transfer of movement into heat is one of those daily miracles. Yesterday it came in very handy.
