Unfortunately, all of them are too busy getting wasted to bother...

When I was in the service, most base clubs the policy was, you wear the uniform you can drink. 18 for those in uniform, 21 for the unwashed rabble.

I'd leave it at 21, it's a small price of three years to pay for several lives saved because of DUIs and other drunken mishaps.

I think most kids from 18-20 have had a few drinks anyway.
