RE: WIll he come back???
Nope, not only will he not come back but I think you scared him forever. You may not have only scared that deer but the others where you were hunting. Not only will you not see any deer but neither will any other hunter because of this.
I'm not tryin to be an arse but come on now....how many of these posts do you see a week? We weren't there to see this. You can say he smelled you, but did he really? Maybe he saw you? We can only imagine what happened. To determine a deer will come back or not is impossible. Sure, it could happen, I've had it happen to me and even killed the same deer. Will he come back? Maybe, but maybe it'll be when you're not there. But each circumstance is different and theres many variances to apply.
