You can bring a copy and then just guard a TV at the venue with gnashed teeth. I usually find it more reliable to, and this is what I meant by "bring your own set up", to just bring a monitor (Evo monitors are lightweight, which is what I used), your own console, and a copy of the game.
And by "Don't know how to use the venue", I mean they expect the venue to run BBCS there for them and then lay out the bait rather than just trying to build a competitive offline scene from the ground up. Xanadu, and MD/VA, is primarily built on Capcom games and Guilty Gear. BlazBlue is new and not well liked by Guilty Gear community here in this location, and the Capcom guys (I'd fall into that category), aren't going to take it upon themselves to run BB tournaments. So it would be up to BB players to use the venue and just keep running tournaments and building things slowly. But there's this expectation that Xanadu should just provide support when it's really just a bunch of guys who've been playing Capcom fighters forever as well as Guilty Gear. Why should they if they don't play it? By using the venue, someone would have to just keep things growing slowly, and I don't think the players understand that.
So BB in Maryland is usually online, but there are some offline players. I think it's just fun to go offline because it's a human element that online doesn't really provide. But I also feel that everyone has a good reason not to NOW because gas is hella expensive.
If you want to find MD online players, just explore the other forums here and look for "MD" or "Maryland" in the location of the person posting.
