That's pretty neat. I used to have a neighbor that had a small amusement rental business and for 2 years he tried to make a ride (similar to the moser spring ride) but after 2 years just gave up on the project all together. He said it was too complicated and that he was going to leave the building to the professionals .
By any chance has anyone been on any rides at a carnival or fair that were built by regualr people in their backyard, garage etc.? I ask because I once rode a swing ride at a fair that was built in the guys backyard... i'll tell you what that was the most scariest experience on any ride I've ever had . That thing was ready to collapse lol.
