I'm sure there is no way you would be able to get anything to drink at the Con. Alcohol laws in the US are strictly enforced. And there is never any booze just laying around at Cons, or drinking in the hotel rooms. All drinking is done under the strict supervision of the Grapevine SWAT team. And certainly neither myself nor the FDBs would consider providing alcohol to a minor, nor do we have any personal experience with such activities.
If you don't come, you will be almost as much of a p___y as Creamo or (I can't believe I'm saying this) Gordo.
