Jeff, what if you're in the room with 6 womenthat are doing nothing but b!+ching and moaning, and one walks by giving the come hither eyes and another guy is dogging her. I know where I'm going.

That's why bucks cruise during the rut. They are trying to find the one that's ready. If they were harem creatures like elk it may be different. Bucks cruise regardless of buck to do ratio, they probably don't have to cruise as far with an out of whack ratio.

That said, the Buck Roar probably makes a fine grunt call when used on the right buck at the right time. Otherwise, it probably won't be any more effective than any other call.
