My folks never "busted" me like that, but they weren't dim to teenage boys being teenagers either. About your age, I wouldn't say they condoned it or wanted to go anywhere near to be acomplices in it, but they were content with a pre-notified, planned friday or saturday night "BBQ" in their backyard with a few of my friends so long as order was maintained and all drivers properly allowed time (hours) to sober.
