Rail riders, not cobblestone. This is groovy (literally) but they aren't really riding on the cobblestone.
Using a dirt boards (with inflatable wheels), people have been really riding cobblestone on actual skateboards for years now. Someone should tell them.

I tried some of these once a few years back. I'm competent if far from talented at riding a skateboard, I'm pretty good at inline skating, but these things I decided after about ten minutes were too dangerous for an 'old' guy like me. There's no way to learn to ride them well without falling down a lot in the process. Not a problem when I was a kid, now: not so much.

In the end, I didn't know what to make of them. They offer no advantage over skateboards or skates and have quite a lot of disadvantages. I guess they're a challenge for its own sake, which is fine since ultimately that's the point since they're not a mode of transportation as skateboards or skates arguably can be.

It's kinda like a combination Heely and skateboard but with inline wheels like rollerblades. Don't get me wrong, I love old school type tricks, but I'd love to see the types of transition tricks and grinds people will start coming up with. Take it from adorable new trend to shredding at the X Games. Awesome new pastime.

They've mastered skateboards, now I want to see kitty roller skates.

As a name, No Rules Skateboarding is sorta like Fishing On Water...

The Jackie Chan of skateboarding.

Unfortunately Newt, the ending proves the officer may be misinformed, but calling him a controlling dickhead is a bit much. There is a concept of "keeping the peace" that could be applied here. He mentions they were "doing tricks" which usually means skateboard-esque jumps and slides which could come into endangering the public.

Also, after the officer walks away, the kid tries to prod him into a real confrontation. The only reason I can see for that is YouTube views or he's just a mouthy little shit.

The Obama one is fake. They used CGI and comped in the skateboard.

skateboards that are this long are just not normal! If you can walk ON your board, it's too long!

51 seconds: Guy on skateboard screws up his trick.

I spent October 21st skateboarding with the wife. Ahhh, 1950s Tony Hawk, thank you for inspiring the future -- even if you didn't make hoverboards a reality.

But really, the fun of skateboarding is in the resistance that the wheels have on the ground. Being able to propel oneself forward and back; tick tacking, drifting, ollieooping (hah), and other fun maneuvers not possible with a hoverboard. I truly prefer wheels, berrings, and the donuts & trucks which support them.
