Ok, I told you all I would correct or update you on something that seems to be completely incorrect about this ride. I say "correct or update" because I am not sure whether an idea changed way back or this has always been the plan.
Turns out, there is no wire in the ride path at all but only passive rfid tags placed every few feet. Every RV is looking for each of these tags to move along the path. I assume each one is numbered. This is why I asked for a closeup photo of the ride path the other day. Apparently, they are reasonably evident if you are looking for them.
I really hate giving out misinformation, and once again apologize for previous info.
