Just got my 14 day non resident salt water fishing license!! woohoo....here's the link in case anyone wants to buy one in advance....$11 + $3 "convenience" fee.....I'm sure you can get one down there somewhere, might even save the $3.....Tried to get one for you Willy but each person has to register themselves with personal info....
