Try coming over and play college in the US. Im from Canada and have done that. So far its not too bad, and in the spring im going to watch two PGA events as im more exposed to them here, instead of being farther away.
By the end of college im thinking youve got to be at least +2 to +4 to really take a good run at it. A good friend of mine is playing on the Canadian Tour and is a +3.2 without too much success. You've got to be a great player, and have an absolute abundance of confidence to even play mini tours, let alone make it to the PGA.
I'll see ya there though;). That's the ultimate goal.
