I must say that this site took me back to my youth at 109st btwn Madison & 5th Ave in Manhattan in the late 60s to mid 70s…I’ve read all the messages! I had one of best “caps” ever made. I found an old school chair,removed the metal floor things on the bottom of the legs and filled them with candlewax. They were almost indestructable, slid great and was so difficult to “blast”.Boy, that was one of my favorite games to play…Thanks for this site and for bringing me memories of those days…signing off, a true Killer Diller!
