I had Aurora slot car tracks and Lionel train set when I as a kid. In the late 60's and early 70's there was several slot car tracks in which to go slot car racing. By the mid 70's they were all gone. As for the Lionel train set which I got in 58 for Christmas. I thought it was gone then about 10 years ago my mom called and said she found everything in the attic. I still have the set.
