Or for those on a budget, we could modify a little clapped-out Ford Escort station wagon, a P.O.S. car I once owned back in the day. We could add a snorkel-type intake for traversing shallow water--given a fast enough start. Suitably rusted, it would be almost invisible when parked along the river. I could use its extra spark plugs for sinkers. The tattered gray carpeting, meanwhile, might offer a perfect dubbing material for the bodies of Adams dry flies.
