Does anyone remember “PUSH-O’S”? A wooden milk crate with a 2X4 nailed as a “runner” with the front end of roller skates on the front and the back half was nailed to the rear of the 2X4. Then you would customize it by carefully nailing bottle caps that could spell your initials, or your street. Sometimes you could get the speed up and crawl inside the milk crate givig the imression that no one was on the PUSH-O.
No brakes, no helmet, no elbow pads…just lotsa fun!!
