Well...a lot of places...most were fishing specific destinations, some I fished since I was traveling through or was not the primary reason to visit.
Alaska, Argentina, Baja (east cape), Belize, Bikini Atoll, Bora Bora (Tahiti) British Columbia, Costa Rica, Ebeye (Kwajalein), Eniwetok, Hawaii, Iceland, Majuro, Maldives, Montauk (NY), Okinawa, Panama, Teti'aroa (Tahiti), Wake Island, Whitsunday Islands (Australia), Yap.
And Molokai, where I lived 2 of my 43 years in Hawaii...and have fished on all of the major islands (including Kaho'olawe) except Ni'ihau...
