IAmA former carnie (worked for traveling midways), i know all about the games and rides. AMA
I worked for Crescent City amusement out of Louisiana and Mcdaniel Brothers in New Jersey. I was a "ride jock" meaning my job was to set up, run, and moves the rides from town to town. I know just about every ride there is but the ones I was in charge of specifically during my carnie career were the Quasar, Tilt-a-whirl, Gravatron (the space ship), and the Star Trooper. I also have extensive knowledge of all the games, how they are ran, how to win them, and tactics used to get you playing. I can tell you all about the carnie life style and put a lot of the myths to rest. I am no longer a carnie, I've settled down and probably won't be going back to it. It is something I miss though.
My proof? aside from the many pictures on my facebook, I can get a job at just about any carnival in the U.S. right now. Here is a link to where carnies find shows looking for workers http://www.carnivalwarehouse.com/classifieds/sub.asp?sub=149&subname=Employment%20-%20Help%20Wanted&cat=30&catname=Basic%20Classifieds
And here is me sitting in the center of a farris wheel, we were working on the lights at the time. http://imgur.com/OnKijvk
EDIT I had no idea this would get so much activity, I've had fun with it. I'm sorry if I missed your reply but I'll be here to respond periodically throughout the night. It's exciting to see other carnies on here sharing their knowledge as well.
