good idea but i don't think they would buy it if twotonevert and i pulled collapsible crutches from the back of the Busa's and started hobbling around
ya never know, plenty of examples of folks with handicaps riding bikes
besides they dont see what you are riding/driving, just you on crutches as you approach the desk asking for the parking permit. they give you a "pass" with a code on it that opens the gates .....
the park rangers on the other hand watching you walk without the use of the crutch....
