Welcome Doug, I had two uncles at Guadalcanal one Marine Sgt. on @ Guadalcanal and one on a ship offshore! It too has been on my bucket list.... I am going in August to the area including "Iron Bottom Sound" we have ONE spot left on the trip! My dive buddy and friend was in the navy assigned to locating wrecks in the south pacific and did a lot of work in Palu... He is a 20 year navy diver. So I am well aware of the rich history and exciting diving in other places beside Truuk Lagoon..
