I grew up in the late sixties. Us neighborhood kids had the 1/64 scale set ups. I still have three complete A/FX tracks up stairs and about fifty or so cars. Raced them last with my kids in the early nineties. Thought about getting them out again for the grandkids. Here's a few I have in a display case and have more upstairs. One of the coolest things I have is a four way intersection.
