I think we need to talk to Phruby about the wall - he was going to try and make very specific angles on it... I'm all for maximizing the space, whatever you guys come up with is up to you!
As for the wilderness area, I don't see why we couldn't have a couple of the vehicles out there, and a few figures too. If we end up with more Rebels than expected there's no reason why we could't have the Rebels all out in the wilderness fighting the Imperials, and as far as battles go - have only the Jedi in the city or a mix of Jedi and Rebels.
If we end up using the Rebel speeder, it could go in the wilderness - and I think that both AT-ST's should be out there as well.
Also - CRAP! I forgot to send the BARC Speeders. I'll do that tomorrow.
