I chased one through a harvested bean field this spring for 1/2 a mile.  At on point I was going 70 mph and when I caught up with the thing it turned left.....on a dime.....then right and kept going.  I slammed on the brakes and set up for a shot with my .204 but he was a 1/4 mile away already.  Darn things are fast.....and must be related to Barry Sanders.
