Impressive home made 1/32 scale slot car track

Here is my buddy Jimmy's slot car track that he has been building for 25 years, it's in the Detroit area and over Thanksgiving I was able to attend one of his events. It is fully function and has four lanes for up to eight cars. He uses AC power and the cars need a diode added. Aftermarket tires help a lot since there is no magnetic enhanced traction. This has been in a few model car magazines.
And yes it is as impressive in person as in pictures...

This is a really different slot racing experience, it is not about speed but more about racing against one another and the track. Note the lanes do not have any space between them but there is a passing lane ( and super complex lane switcher!).
