Four square competition in Pittsburgh?

Hi,

Back from elementary school, when I played every day with students in my class, from 9 years we played. I have not yet stepped on a four square court in a long time. I used to have all the tricks, or at least the one's in my school. Seeing as I haven't played in a long time, I would like to see the population of players in the Pittsburgh region in hopes of getting a competition, or just some friendly games.

Anyway, thanks,
Graham
