I suspect you are probably right. Vendors all have skin in the game when it comes to vending in my opinion. It's also an issue exclusive to SoWal because we don't have vendors up here.
I have noticed that there seems to be a push for parking at beach access points for golf carts which again in MY OPINION would create a conflict. With everything else they are going to allow on the beach it may be just a matter of time before you see them there as well.
I would guess they are doing golf cart parking because 1 CAR parking spot equals 2 GOLF CART parking spots and since SoWal is becoming more and more golf cart friendly why not? Its called forward thinking.
