That air scooter looks like a hoot! Probably slightly more risk than an
out-of-traffic-motorcycle. (Oh boy--me on just a bicycle is enough
entertainment for the neighbors and don't get me started on the new "Land
Rollers." As a child I never learned to skate but at age 42, I discovered
this great improvement to Rollerblade technology and spend four days at
"skate camp for middle-agers" in Hilton Head. (Okay--old farts.) What a
blast! I look like the Michelin man, but I have a great time. I highly
recommend "Land Rollers" to anyone who likes the Roller Blade concept but
appreciates small companies implementing better designs.) Anyway, for the
air scooter I'd gear up as for motocross, train-up and have a blast! (No
wind blasts, thank you.)
I appreciate your interesting information and your kind response.
