A smart skater is a male/female person who takes reasonable precautions to prevent them self’s from getting hurt. Such as wearing a helmet and wearing clothing that allows mobility. That covers your skin, especially the legs to prevent scraping them self. Smart skaters also wear elbow pads & knee pads when doing something extreme. When a smart skater gets badly hurt they take a break & or get help.
A smart skater knows that they will get hurt when attempting tricks, they are simply not being stupid.
