An idea I've heard about for a few years is run on the salt flats about 5 miles north east of where we run now. Something like 20 miles of NaCl out there, 'cept you can't get to it for the mud. Might be "simpler" to build a road out to it. Of course that assumes you could get the enthusiastic endorsement of the Sierra Club, the EPA, the BLM, NSA, FFA, FBI, DOD, CIA, WTF, FTC, FAA, KGB, NRO, DHS, NBC, ABC, PBS, ETC.
But it IS out there.
