Why don't park rangers enforce campground ban on alcohol?

[hockeybuff]

Having a leisurely can of beer or glass of wine at dinnertime (or any other time, for that matter) while camping inside a state park can draw heavy penalities -- or so we're told. Yet, the dumpsters are overflowing with empty alcoholic beverage containers .... presumably to noone's surprise. Is this a law that is only enforced secondarily, when the individual has also misbehaved in some other way that is less well defined? This sounds like a Catch-22 trap to me!

Any official explanation would be appreciated!!

I am not an official but am curious why you care? How have you been harmed by finding a lot of empty beer bottles in a dumpster? Are you looking for trouble? Check with a park ranger and file a complaint if you wish to pursue this...Your question puzzles me.
