Looks like The Widomaker which is about 50 miles South of SLC Utah... There have been some INCREDIBLE runs and crashes down there over the years...
I think they shut down the Widomaker (which is located across the highway from "Point of the Mountain" State Incarceration Facility) abotu 10 years ago or more... Maybe they still do it though.
