The CVS golf classic is down here at R.I. Country Club. I think every year. They have been using a fenced in paddle tennis court as a cage for parking. (Smaller than a regular tennis court, and fenced in better.)
I heard they had tickets, one for the bike and one for the rider. I think that's all there is to it.
It's not really valet, but the other person does put your bike away for you. But you are right in front of the parking cage.
