In the wrong scale.
These car lanes are half as big as they should be. Way back at the start of this project, I decided to stick with the Division 5 cars. The problem is that Division 5 cars are rated subcompact, and the 1" wide bases are too small to hold a m1:64 scale How Wheels or Matchbox car. So I upsized the scale by fifty percent to make it work. When I started the highways I used the old 1" = 1 lane rule.
Like an idiot I didn't check the terrain against a reference figure. I just plowed ahead with base measurements. When your miniatures don't meet the terrain until two months into the project, you know what you get? A lot of useless terrain.
The trees and billboards can be salvaged, but the boards themselves? All that time and effort and paint and static grass (which ain't cheap)? Wasted.
Maybe I can pawn them off on some sucker at a swap meet. Anybody know any suckers?
