Got to take my 73 Polaris TX500 limited (survivor I500 race sled) around the I500 track a few years ago prior to the start of the race. Pretty neat experience. This was in conjunction with what they called "memories on the mile" vintage sled show. I don't believe this is an option any longer.
My Dad could find great ways to destroy tools we all would love to have as he had no idea what to do with them. We had a "shade tree" mechanic next door that would help me on our mowers, sleds and eventually vehicle repairs. Then in high school we had auto shop and builder's trades that taught...
A friend of mine has I believe the 50-year anniversary poster that shows the hay equipment piece, power washer and a year-by-year sled spread that I'm sure others have seen.
