I rarely see the "cover the spot" and "wacky wire" in my geographic area (DE, PA, NJ, MD).
The wacky wires are on display every year at IAAPA and IISF.
The wacky wire is manufactured by DOBCO (Dobson) of Canada (I believe they also book games with Conklin, and possibly others).
Dobco also makes updated, themed versions of the wacky wire- Wizard and cobra.www.dobco.com
Come to think of it, I don't see many cat racks anymore (on carnival midways anyway).
On the other hand, I don't have far to go to see "start and stop" wheels (aka "stop and go", "color" etc...)- There must be more start and stop wheels along the New Jersey shore than anywhere else on planet earth (at least the "Jersey" wheels)- there must be more than a hundred of them along the boardwalks and piers in Jersey.
Of course, a lot of that has to do with the fact that most of them were manufactured by Park Sales of Seaside Park, NJ (not to be confused with the "Pennsylvania" wheels manufactured by Jack's Games of PA). [:D]
One unique game I remember seeing that I don't recall ever seeing, was last year on Reithoffer at the PA Fair in Bensalem- it was a game in a line-up trailer that had several large old wooden "pinball" machines that were flashed with a variety of merchandise from slum to higher-end merchandise. The slot your ball went into was the prize you won. I thought that was a kinda interesting game- rarely seen. (Unfortunately, when I tried to photograph it the guy working the joint abruptly stopped me and said "Yo, Buddy- If I let you take a picture of this, I'd get in big trouble. My boss would probably fire me." (apparently secrative game)[:(]
