Although I agree with everyone about murder weapons, I cannot for the life of me understand how a bicyclist could have mouthed off about corn cobs being in the road! If he doesn't want corn cobs, he can ride in the city and worry about broken glass!
It sounds to me like there are attitude problems on both sides here. When we ride in farm country, we wave at the farmers and count the onions, pumpkins, corn cobs, etc as "road kill" and laugh about it. Sure, any of those things could cause us to wreck our bikes, but that's why we have eyes...

Silver, good luck with your officials. It sounds like you have some bikers there making it worse for everyone.
