I went to Pennsylvania this past weekend for a conference. $118 for a three-day car rental got me to Pennsylvania and back (and some driving across Pennsylvania in-between, to pick up a cousin). I put 1450 miles on that car in those three days (23 or so hours of driving).
The conference was wonderful. There were a pile of historians in the group, and we all convened to workshop each other’s major projects. The consideration for new ways of thinking across our disciplinary boundaries was wonderful, and by the end of the day we came away with full minds and a lot of wheels turning.
