In line skating is a multi disciplinary and is a sport that's practiced all around the world
I didn't realize it was that popular. Where did it start?
Yeah its very  popular .  Not much info on that but i did find that inline skates typically have 2 to 5 wheels
I wonder if they have a brake pad too like roller skates?
Not much information but it does state that in line skates design does allow for much greater speeds
I wonder if they have a contact sport like roller derby lol
Not that i have found ha but that would be great to watch.  In line skating has another name called roller blading
Makes sense, roller blades have a single line of wheels, so...inline.
Yeah , another fact is that vert skating is a form of gymnasitcs
What is vert skating? Like on a half-pipe?
