Tell me about it. LOL! That's why I'm trying to make the decision now. If I wait until one of them is standing in front of me to decide there's not a chance in hell I'll let them go.Anything could have happened. He may be dead. He may have been pushed out of primary bedding area and was passing through looking for a new hideout. There may have been a straggler doe in heat very late in the winter somewhere around and he was cruising. The possibilities.
If you can move your cameras around and maybe throw some corn or a salt lick on different trails you may find him yet. Either way, considering the size of your tract I would consider busting one of the others if the opportunity presents itself. Things could be much worse. Or you can let them walk to grow another year. That will take some discipline, though...It is easy to say you will let them walk, but when they are right there in front of you it can do weird things to your decision making. LOL
