just saw this thread pop up on the forum activity email...
... oh, my gosh... what memories... i was big into models too. lots of mashups, rarely building them as intended. couple of my favorites were the boothill express & the big red baron (1/12 scale).
i'm so glad i found this forum.
I'm looking forward to the next bash up. I'm going to take the same approach as last year, and start with a small scale model (1/43 or 1/32 prob), and then raid the kid's toys for a character to stuff into it. That was fun.
