Bowhuntinfool,
I filled my anterless tag a little over a week ago and would've bet anything it was a quick pass thru. Couldn't find my arrow close by, so I went to get the doe, only to find it clinging to the exit wound by the vanes. Anyway, it's possible you need to follow his running path and that the arrow fell out during his final run. If this was in a farmer's field, spend a little extra time looking, as the broadhead could raise hell with a tractor tire. Try using a steel tooth rake perpendicular to the direction the arrow was shot, in the area you think it might be. Good luck, and congrats on the buck!
