This week's Poetry Slam (Monday, 8:30 PM) at Cafe Deux Soleils is a "Nerd Slam". There will be costumes. I don't know if I should be terrified or excited... but let's go with excited.
High Altitude Poetry is turning it into a social outing for the group, and I think I'll wander down the street and join them - you should too!
More info on it here.
