So according to that he'd need 10-30 sets of skateboard wheels to cross the country.
Of course if you're just riding on the side of highways in a straight line forever you could probably get a little more out of them since you're not doing any precision work or tricks.
Not so sure. A road surface tends to be rougher pavement than sidewalks or skate parks. I'd imagine the side of a highway chewing those parkboard wheels away at record rates.
I'm honestly kinda shocked anyone attempting this wouldn't use a longboard with some chonkier wheels.
This one's not going to be close. According to his youtube channel, he's on day 50 in Kansas. Got a Red Bull partnership and enough money for hotels & Uber for off-trek travel.
