RE: I feel dumb right now
NY,
Typically, white hair isn't a good sign of a good hit. Re-climb your stand tomorrow and get your dad to go to the place where you think the deer was at when you shot and look close for your arrow and any other signs. If you dont find anything, send your dad to the last place that you can remember seeing the deer before he went out of sight. After you get out of your stand and meet him there, you guys look really close for any signs that the deer might have left.
Hope things work out for you. Maybe with a little luck you will be able to determine how well the deer was actually hit. If you guys determine that it wasnt a deadly hit, atleast that deer could still be around for another shot before the year is out.
Good huntin'
