The Racers Circuit #4 Hillside

While unpacking some Exhaust fans for a project, I found some trestle shapes in cardboard, so I went at some hill/elevation work, very fun and maybe more permanent if it works out well, Let's take a look,

I could make the trestles all flat at the same elevation but what fun is that?

Here I used Full sheet foam board to keep things flat during this turn, then....

Down we go to a tight left, good times

Video? Ain't very good but you'll get the idea
