Can you get good at surfing, like real good, only surfing the East Coast? Not travelling to the Carribean, Hawaii, or anywhere - just having been born, and raised, only surfing on the East Coast? OK one week per year travelling allowed. If you are 'on it' every time there is a swell in the Northeast, is that enough to rip?
the only way to get better surfing other areas is to surf other areas... You cant really expect someone who has only surfed the east coast get dropped off at pipeline and shred it to pieces. Every wave is different. Traveling to other spots will make you better.
