Although I usually paint in oils during plein air competitions, 2 full days of pouring rain for the Gunpowder Falls Plein Air event  (www.GunpowderFallsPleinAir.com )  forced into my car to paint and made watercolor the better choice. With a watercolor board against the steering wheel and my paints and water on a beach towel on the passenger seat, I made the best of it, every so often running the wipers to clear my view. Hereford is a little town in the North Baltimore County area of Maryland, and I liked this view with overhead traffic lights and car lights reflected on the wet pavement.
