I have fished out in the Ocean several miles offshore of there the fish schools are huge. The Gulf is too dangerous!
That flat like fishing is pretty Kool try some wogs and a dryline they explode on the surface from time to time. When I lived in Sitka I fished several places that had a similar situation and it was great sport wading and sighting and casting and catching. Good Luck I think I am envious already!
Seriously you are going to be in a very rare place you will no doubt enjoy the fishing but Icy Bay is about so much more you will be spun by the immenseness of the place.
