'bout one a month or so a group of us gets together and we bring beer, booze and snacks and play some poker. $20 buy-in Texas Hold'em (Prizes for 1st, 2nd and 3rd), then $20 worth of Dealer Calls the game. Figure another $5 a head for pizza and your out ~$50 for the nights entertainment. Good Friends, Good Conversations, Lots of Laughs and you may even pocket a couple of bucks (or be out $50 at the most).
Cheaper then going out for a good meal.
