Here's a replica of the old Greenwood Roadway, located in Iowa. It's 176m longer than the original circuit but it's very hard to recreatie the original 4800m length with forests around it. The Greenwood Roadway operated between 1963 - 1966 but continued for amateur races till the early 1970s.
I love this track! Being from the Midwest in the US, I love the idea of going down to Iowa to race some of the best exotics in the world :D The track is fast but still difficult enough to warrant precision at every turn. Thanks for being a great track creator!
