This is going to get NO sympathy from anyone, and probably no agreement from anyone, but ... minimize drinking if you can is my opinion. (Easy for me to say -- I have a 1 drink maximum these days! Sigh....)

Anyway if you can't do without, EAT YOUR EMPTIES!!!! We will need to have zero tolerance for beer cans, brandy bottles etc in the trash receptacles.

It is awfully hard to find a good camp and IMO if they are really serious about no alcohol there's just a chance we might be personae non gratae in future if they notice it.
