What kind of bales are we talking about?
Square bales........the pilot would have a hard time running, more a waddling motion.
Cotton bales....well, he better be strong....or have a Jeep and other troops to load his baled self up and haul him to the maproom.
Round bales.....this I can see........just imagine a round hay bale rolling along toward the maproom. Of course, HTC'll have to make the maproom doors wider and taller to get 'em in. Be hard to aim your .45 too, rolling and rollin and rollin........they oughta add dizziness into the equation too, just to make bangin away with the .45 more of a challenge.
