Played at Badlandz once, I won't be going back.
I keep meaning to give Fox Piantball a try, but I haven't gotten around to it.
I hope to make it out to Realms for the Siberia scenario; that will be my first time there.
I wish I knew someone with some land that I could play renegade ball on. Paint prices just seem to be ridiculously high at the fields around here.
There's an indoor Reball place that opened in Elmhurst (I think) that I might check out sometime.
