Read the introduction from an opinion essay. Have you ever wished you could ollie or kickflip? If so, you must love skateboarding! In case you don't know what these words mean, they are different skateboarding tricks. An ollie is when you jump into the air with the board, and a kickflip is when you flip the board over mid–air and land on it. Some people skateboard for fun, but others are professional skateboarders who take part in competitions. It is also a great way to travel. Longboards are stable and go fast enough to get you anywhere you want to go.
