Panhandle of Texas
Simular to what other people here in this thread have described, I too have heard of old tractor "driving" themselves. The tractor followed a deep furrow made by the plow.
If MythBusters investigated it, I know it would come out as "True" because I've heard toooo many old timers talk about it.
