Unless you've got private land or a secret honey spot I'd say elk are one of the toughest animals to hunt. Success rate here in Utah for the general hunt on public land is 17%. Some guys get elk every year but thats only because of one of the above reasons. I don't know about your hunting low theory. I hunt the high country (10,000 ft plus) and thats where most hunters go around here, any fool knows when its dry and warm the elk are up high.
