Skateboarding is an action sport which involves riding and performing tricks with a skateboard.
How much balance must a person have in order to ride one of these skate boards? I would be afraid of getting hurt.
It is also  a recreational activity, an art form, a job, or a method of transportation
I imagine that would be an effective way to get around. Does the person need to wear any safety equipment?
maybe, a 2009 report found that the skateboarding market is worth an estimated $4.8 billion
Tony Hawk is on of the greatest skaters of all time correct? I wonder what his biggest trick was while riding.
skateboarding will be represented at the 2020 Olympic Games in Tokyo, Japan.
I didn't know it was an Olympic sport.. Will the USA have a team?
