I really don't like the idea of adding admin stuff in such large amounts. Glass block is fine with Brad's 'clear' texture, and really, how many times are we going to walk that 16K path? Not many I'll bet.
OP stuff freaks me out. Just sayin'.
Again, sorry about having to cut my adventure time short. But did y'all see the lake I mentioned upthread? It's nice.
If south is the direction we decide upon going I think that'll make a nice 'home away from home' area.
