listening to a turkey gobble at night knowing you're hunting him the next morning is just plain fun. I have some spots I know thespecific trees they like to roost in but will still go out night before to listen to them.

I also have stood on the back porch and made any crazy sound and got them gobbling in the evening. Crazy things. If they decide to gobble that night they'll gobble at just about anything. One night I yelled "night night" and three gobblers sounded off (I wouldn't recommend that. they were just crazy loud that night)

I truly don't believe it's a necessary part of my hunts but I do enjoy it. You can roost them in the morning and a good turkey hunter can make a move to get on a bird. That can be exciting as well.
