Pete,
I've got to get after them again some time, I have a score to settle with those ornery little buggers. A few years ago one ran off with one of my laminated birch arrows and grizzly grande broadheads. The audacity of the thing...
They are tough, that's for sure.
The archery club I belonged to in Nebraska would give away the pieces of 3D targets when they replaced them. I had half targets of almost all the smaller animals to shoot at one time or another...usually the rear end, but not always. Is that how you got yours? I never thought to attach the head to the back though, that's slick.
