Dunno about instant gratification, but I don't know of any situations where the majority of deer hunters in any given situation didn't get upset when management strategies were introduced that resulted in decreased liklihood of bagging a deer, in particular nice bucks. Hunters in general are not too patient with short-term pain for long-term gain. That is especially true for deer hunters, many of whom never quite grasp the concept that modern deer management has many other responsibilities and goals beyond maintaining deer populations at levels that will make all of them happy.
