Longboarding is a great way to stay in shape for surfing man. I am a skateboarder but I always admired longboarders for their balls. These guys ride with 100 km/h lol!
I think you will easily get the hang of it man, that's what I see judging from how fast you learned to ride!
You should check out @howweroll. He is a beast on his longboard. He is a speed freak! Hahaha.

Just followed you and I am waiting for more.
Much love and #SKATEFORLIFE.
