So I guess I'd probably be giving out lap dances and strip teases once I got bored of everyone not being crazy. Halfway through the party I'd be pretty drunk and all "KAY FUCK Y'ALL I'MMA GO BETTER PARTY ANYWAY" then come back an hour later with a bunch of pool noodles and be like "OKAY NO BUT REALLY NOW I HAVE A GREAT IDEA GUYS."
See, I forget punctuation in my speech when I'm drunk.
Anyway... doing an average of locations by post count is silly, because some awesome people only have like 810 posts, while other non-awesome people have like 2574 posts. What you should do is do an average of locations by who is coming to this party. Obviously Lowell wouldn't, so including him is silly, even though he has a bunch of posts. So the only way to know where to have this party is to know who's coming.
