On3?

I did On30 for a while, but my caveman hands are really too big, so I switched to 1:20.3. That's Fn3 which runs on 45mm G scale track. On3 is really cool and challenging, since no one makes ready made track and you have to hand lay track and ties. I've done it before helping a friend on his On3 layout. It's really cool because you can lay the rails and ties imperfect just like the real thing.
