We used to buy kegs, at legal ages and before, and haul them out to an island, we called "Kegger Island." It was an island in the middle of a nature preserve with a wooden bridge going to it. It was far enough away from houses, so people didn't call the cops on us. (It was also too far away for any cop to try and catch us, and we could see anyone coming from a mile away.
Those were the days.
