I have pleanty of good themed terrain for a venue the size of Scifi City. LOS blocking, difficult ground, to area terrain. Forrest/Green Hills, Badlands/Desert, Mountains, and Jungles/Huts. All neatly packaged in filing boxes for safe transport.
Mix it in some of the material already there like Matt's 40K building or the river sections (wonder if are the same ones from WoHoG and Cincinati Scifi before that) and the boards will look sweet.
Of course having more terrain for any gaming day down there is even better.
