Enchanted Forest had a set in Chesterton, Indiana. I was an Op at the one there. Man, people would get really stupid in the cage. We had alot of company picnics where they had free beer. The drunks would get in the cage and get in going pretty good and all of a sudden they would lose their balance and get tossed around like a rag doll. Good times. :)
Myers Lake Park in Ohio had one for many years. I used to ride it all the time. You really did get knocked around a lot, but that was part of the fun (at least back then before people sued over anything).
Knoebels had them up until the mid/ late 80's where their handstamp booth is now! unfortunately I never rode them but hear all kinds of GREAT stories about them. People having fun then loosing momentum from laughing then getting hurt getting thrown around in the cage!
Sounds like fun to me! Especially with a few beers, or maybe not!
Argh! Torture devices! When I was kid they had these at Blackpool Pleasure Beach and every year my dad would make me go on this with him then make me feel like an utter wimp because I never managed to get the thing over the top!
Not sure about mainland Europe but I am pretty sure there aren't many left in the UK.
One of the local carnivals used to have these every year when I was 7 or 8. My mom would never let me ride them though. Probably a good thing from the sound of it. We always used to think that riding this would be the eqivalent of getting a swing to go in a complete loop.
I believe it was Sport City and the place closed down a year or several ago. I'm not sure when they last used the swinging gym but I remember people talking about it. I should have made the effort to check it out.
