Public hunting falls into the same category as public fishing. How many times have you been fishing and another boat comes speeding right by your boat, making no effort to slow down and circle around at a polite distance even though they can see you are fishing?
In both hunting and fishing, there are X number of people who are informed and courteous, X number of people who don't have a clue, and X number of people who have a clue but just don't care about showing courtesy to other hunters/fishers.
I'm in my 50's, and it seems to me that the number of people who show no courtesy to others has risen dramatically over the years. Maybe it's my imagination but I don't think so.
