At Norwalk the track has a vendor that rents carts with the Bader families full permission/blessing, If the track owners feel comfortable having a vendor renting carts (Only to licensed drivers), why would the participants second guess the owners of the facility????
If you read the rules about operating the wheeled vehicles the track can confiscate a vehicle from someone not obeying the rules of the facility.
I really have no problem with it, and as MA has said there are much more pressing problems than worrying about wheeled vehicles at show and race events. It's a convenience to be able to use a wheeled vehicle at a large event at a 200 acre venue, same as a cell phone is. Norwalk has allowed wheeled vehicles as long as I've been going there (1996), I doubt they're going to change their parameters of their events, feel free to keep beating the horse, I doubt it's going to get up and run...………...
