Red Bridge Road Bridge
Posted March 15, 2016, by Katy Merrifield (katydidditt [at] juno [dot] com)

Sunday, March 13, 2016 we were scouting the Buffalo Creek to possibly paddle and checked out the Red Bridge as a possible landing. Much to our dismay both sides of the bridge were littered with carcasses--2 coyote, a deer, an unidentifiable mess of fur, and the gutting of a deer. Disgusting! I will be calling the Lin Co Conservation office next. Why don't the hunters just dump the carcasses in an empty field?
