We are not rabid drinkers and we don't get drunk. However, no camping trip prep is complete until the beer and ice is loaded in the cooler. Virtually every campground we go to has rules of some sort related to alcohol, and since most are state parks, the rules lean toward prohibition. But we've walked around every campground with either an open bottle of beer or a solo cup of beer and never had even a mention by staff, rangers, etc. So as best we can tell, alcohol rules are only in place to give the ruling authority leverage to deal with the often times bad situations caused by drunks and partiers.
