What is this thing you call poetry slam?

Loosen up those lips and sign up to join in Saturday night's Poetry Slam at Synergy Cafe, in the Vandehei Plaza at 459 Vandehei, at the I-25 and Vandehei exit. Sign up at 6:00 p.m. Open mike begins at 6:30 p.m., with the signed-up slammers beginning at 7:00 p.m. Bring three poems to compete and win weird, inexplicable prizes. Takes place in conjunction with the Wyoming Book Festival, September 14 and 15.
