Poor trip planning, didn't pack underwear for day 2. Washed what I had in the basin, then nutted out a way to dry me 'derps.* The motel room has an electric wall panel convection heater. I positioned both forks from the kitchenette in such a way as to stretch the pants above the hot air without touching the heater itself. Job done, they're nice & dry.
*'derps = un-derp-ant-s
