oh yeah......those skinny wood boards, painted red, with the steel wheels. Seemed to be sold by the millions. The 'improved' clay wheels that we purchased and installed on our own home made boards would also seize up on the smallest pebbles. These stories remind me of the 'Flexies' or Flexi Flyer. I know those have also been discussed on the Message Board. To some extent, I am thinking that these early hazardous ventures morphed into some of the 'X-game' style activities that are so popular today. Not an especially big fan, but quite interesting just the same.
