That could've been me in the photo w/the police. Several kids in my neighborhood had minis and the police were always after us. Turned out that the deputy who we thought just hated kids retired with great honors for his efforts against child abusers. And one of our gang became a deputy in the same department when he grew up and went on to lead the county's search and rescue team.
I broke that pipe frame and rebuilt the machine using a $10 frame from Boy's Life Magazine. I don't remember what happened to the pipe frame. I hate to say it, but it probably got pitched in the trash. I later broke the $10 frame riding across a plowed field.
