In mid 2024, the origin of the back rooms was found to be https://web.archive.org/web/20030503094137/http://www.hobbytownoshkosh.com/revolution%20raceway,%20020903.htm All the photos have perished except for the 2 back room photos. It was an upstairs room in a long defunct hobby shop. The store managed to survive 2020. It would have been a good place for someone with some imagination & money to take a peek. There have been some 3D models, but the original interior seems to have been gutted. Someone made a video in 2024 & the store still existed. It's probably sustained by air venture.
