I enjoy inline skating, but it doesn't seem to be as popular. Do you know much about it?
a little, I do have a pair somewhere in my closet
Awesome! It's different from quad skates which have two front wheels and two back wheels. I enjoy my roller blades. 
who came up with the ideal of roller blades?
It was actually created to substitute ice skates for Russian athletes! How cool is that?
it sounds logical when you do not have any ice to skate on
Inline skates
Inline skates are a type of roller skate used for inline skating. Unlike quad skates, which have two front and two rear wheels, inline skates typically have two to five wheels arranged in a single line. Some, especially those for recreation, have a rubber "stop" or "brake" block attached to the rear of one or occasionally both of the skates so that the skater can slow down or stop by leaning back on the foot with the brake skate.

liked to work from my imagination. I like to work from a fact, and I will try to make something out of the fact. I enjoy that most. And I do my best work when I do that. I don't know whether it's just because I put it out of my mind that I don't like to make things up. Some artists are marvelous at just fantastic inventions. But I love the smell and the feel of life. You have to follow your appetites. You don't choose
