SURF is in Petalburg City, you get it from Wally's parents in the house next to the Gym after you defeat Norman.
When does the game allow you to play that leader because that one is the father and he just says that he can tell oyu have gained experiance or whatever I don't remember..
And thanks for the other help both of you
if you need help with any just ask
