I think we should get the 2 10' ISO's if someone can acquire DRMO stuff. It would give us either a 10'x16' stand or a 20'x8' stand. 8' tall. I like the 10x16 idea as it gives more space on both track sides.
I don't think a built stand is an option. It would have to be anchored down, which means putting posts in the ground which would probably require a dig permit.
Even though scaffolding sounds like a good idea, I can't see safety buying into that over an ISO....
Great pics Rob!
