I'm glad not all of those big guys go to waste.
I'm one of the bugs and bunnies guys and can confirm we haven't had one come up hot yet. Granted, we don't do any internal rad surveys, but we hit their hooves, mouths, and butts.
Its been a decent year so far, haven't had a ton of road kills. Last year we had 6 big bulls whacked in about a month. Always a bummer.
