I'm building this:

Actually, all the pieces are done.
I'm not too happy with the build. It's the first time I've built entire wall sections that needed to be fit together. Variations in block heights really impact this. Bruce's old FS blocks are fractionally taller that the new FS blocks (He didn't allow for the height increase caused by the glue holding the master in place.) Since I used a mix, this really messed me up.
Normally, I build a row at a time and fix odd blocks as I go.
Another HUGE mistake I made was using Aleen's (sp?) Tacky Glue. It's got a long set time and I'm used to the concrete like hold of Weld Bond. Pieces that would have been set in minutes normally (for me) shifted or fell apart. Really, really annoying.
Painting this beast without the sections would be a pain but I'm still thinking about it.
Now that the bits are done, I have to figure out basing. I don't want to do the raised foam base like in the instructions. I bought .25" MDF in a 2' x 2' sheet and had it quartered, so I have 4 12"x12" sections.
I have a thought that if I make a bunch of 12x12 terrain sections, I can make a modular city... still playing with the idea.
