I've been watching vids of them building the track and it's like was said above. Gundaker building the track and it being 7000 Cubic Yards of the same they use for Supercross. It looks to be built right, layered, watered and packed at each stage. Should have a few practice vids up either tonight or tomorrow on Facebook.

It'll be a challenge to keep a LM on the bottom of that track as the inside is no bigger than Du Quoin's the outside looks racy If your going to run the bottom at St. Louis, They'll be backing them in.
