If I remember correctly, there was a golf course in Glenview or Morton Grove, Golf Road/Harms Road area that allowed snowmobiles on the property, legally. We would ride there on the bike/horse trails from the Niles area of Howard and Caldwell by Tam O Shanter golf course. That was a pretty long cruise for 15 year olds, in the dark.Sounds exactly how it was for me too. Grew up in Glenview. Our house backed up to the forest preserve so we took the horseback riding trails to the Wilmette golf course and bike trails. Cops would try to stop us at the road crossings but couldn't catch us. They never had the desire apparently to follow the sled tracks back to our house. It was fun for sure.
