we're renting a car only because if we decide to start running around, it'll actually be cheaper. we found economy cars (ford focus, aveo, etc) for $16/day on orbitz so that's the route we're going. we'll be staying about 10 min away from the venue so we're up for meeting up somewhere friday night...
if no one else will, maybe i'll look into organizing something even though i don't know a thing about pittsburgh
