There arent many parks around so our explanations may not be the best but park is usually a lot more chaotic than any other type of riding this is because there are lot of people riding close together. Courses can get really hectic so if you are looking to do well keep your cool and always wait your turn. Ramping is very fun your can pull of a lot of cool tricks and I myself enjoy it.
Follow the parks rules
Wait for your turn
Wear your safety gear
