Point taken. I edited my post (perhaps you'd do the same). I kind of don't think venue security is reading up on 'places kids stash their, uhm, stashes', but whatever.
The word police can have some.
I submit that either:
A) the fact that concealment was attained by using information makes steg an appropriate word,
or B) Booze is information. It can be, at least, informative.
But again, whatever.
