Because at Dland last Sunday, VFan and I were nearly run over by a gaggle of about six 20something kids in a line and MAYBE one of them needed to have one, but certainly not all 6. How do I know? Well, ok we didn't ASK them if they needed them, but the way they were plowing through Adventureland, they way they were sitting on the scooters, legs crossed or up on the steering mechanism, I’d venture to guess if they had issues they wouldn’t have been driving around in those positions.
So, CAN any Tom Dick or Harry rent them? I mean personally I don’t think that’s right, because then you are possibly taking away a scooter from someone that might ACTUALLY need it.
