Horse Poop Bonfire! Redneck?

We spent the day clearing out the Mini's pasture of the downed trees and other miscellaneous stumps. We burned it right on a big pile of horse poop. Brandon got out the marshmallows and roasted a few until he decided they really didn't taste very good. I am not sure if they did not taste good because they were old or because he was roasting them over wood that was burning right on top of horse dung?! He said to me, "Mom, these taste nasty, here try it." Ummm, no thanks!
