Unlocked, don't listen to Mr. A$$ Hole (as I like to call him) he does nothing but shoot people and their ideas down. As for the buck, he might come back, he may not. The only way to find out is to keep checking the camera and start scouting. I don't know if you have already, but walk your property. Look for trails, their natural feeding grounds, scrapes, rubs, droppings, things like that. But don't over do it. Pick a day and just do that day, don't consistantly go in and interupt them. They don't like that haha. And with a mature buck like that make sure to use some scent control. He's gotten that big by being a smart deer, as you said your neighbors will shoot just about anything haha. But yeah, start figuring out where the deer are and where they like to be...he's been there once, my bet is he'll be back. Good luck!
