It is quite sad that some will go so low to steal another hunters deer. I have never had this happen as last year was my first. I have no input on deer that are still on the move but as for deer that are down and already tagged or gutted. I read a post once by a man that said he always does something to make sure he can prove the deer is his if it is taken before he gets to it. Such as putting a small coin or even a candie wrapper in the deers ear or nose. Sounds a little strange but as often as hunters leave their deer to get a truck or atv to haul it back to camp it could save your trophy one year
