yeah i guess it can be similar to rollerblading depending on the grinds and grabs and stuff, but you can make it similar to snowboarding too, but from experience i know it is closer to snowboarding,  rails are just as hard, spins are almost the same, we ride on the same thing, snowboards are just bigger. and because we are on boards we can press, butter, and do all this cool stuff just like snowboards, that will never be possible on rollerblades.  and the difference on rails is soooo  huge, we are facing the same way and thats pretty much it. no skier will ever do a 36 kink rail or whatever, or a 666 foot rail on skis, its impossible.
anyway thats if you want to compare it to something else, i hate comparing skiing to other sports, but if i had to say which sport its closest to, it would definatly be snowboarding.
instead of worring about who we look like and all this crap we should be doing our own stuff, thats why i dont like all the rollerblade style stuff charles and other people do, rollerblading and skiing are two completely different sports. and i dont think we should be copying snowboarding either, but because we ride on pretty much the same thing its kind hard not to.
