Stay on the left side of the road, apply the horn liberally, and trust in Vishnu.
My most memorable shuttle involved a bicycle and a bad map. I studied the map and determined that there was a road coming out of the state park that would shorten my shuttle quite a bit. Problem was, the map was wrong. Not only was there no road but a flooded woods on private land. Not one to backtrack, I pushed the bike through up to knee-deep water and eventually made it back to a road. The bike was festooned with water plants when I finally rolled in at the put-in where my mosquito-bitten wife was waiting to give me a tongue lashing.
