Utah Motorsports Campus
I was only lucky enough to visit Utah Motorsports Campus once during all my years in the USA but what a great facility! Formerly known as Miller Motorsports park it lies just a few miles out of Salt Lake City to the south west.
In addition to a great circuit with very friendly people I will always remember it for having the best on-site catering I have ever had at a sports venue.
Photographic access is very good but, as is often the case, you will need a 400mm to get tight on motorcycles.
