when i was in college, i had to write an article on the new skatepark in town for the newspaper, and i interviewed this kid who was riding a razor scooter on the park's opening day. he was about 10 years old and was cutting skaters and bikers off, riding through the bottom of the halfpipe while people were in it, just getting in the way all over the place.
he told me he was probably the first or second best scooter-er in the whole town and can do tricks. then he did a "bunny hop" about 2-4 inches in the air, but didnt land back on the scooter with both his feet. he only got one back on and just stood on the ground with the other one.
therefore, scootering is harder because there were tons of kids on rollerblades doing difficult looking grinds and getting decent air out of the halfpipe, but the first or second best scooter-er in the whole town of 15k people was still having the toughest time with bunny hops.
