Thanks! I hope it turns out nicely...want my players to have a good experience with the game so I've been kind of going all out.

I just went by Office Depot and picked up some pretty cool poster board...it has a barely visible (to me anyway, maybe someone with better eyes can see it) 1/2" grid on it. Sadly, it's only 22"x28" so it won't cover quite the same ground as the larger paper (27"x29"). The bridge is 14" across and it's about 22" from the outer edges of the surrounding hallways fore/aft and port/stbd. Still, it'll be a nicer finished product I think. Hopefully I'll get some work done on it tonight.
