You know I'll be there
If a lot of people end up showing up - IMHO the beer would probably be a bad idea. JMHO though! Lots of cars with exhausts and lots of people standing in the parking lot will bring out the local police (which I have absolutely no problem with - so long as they are only making sure that we aren't a bunch of hoodlums). With open containers (obviously against the law), the little get together would be over really quick.
... that said, if we only have the 4-people turnout that we did before, then drink away
... so long as you don't plan on driving after drinking a few.
