I've been to Iwo Jima, including the top of Mt Suribachi, where the flag raising memorial still stands. And I've been to Midway twice. Once when the gooney birds were all over the island and once when they were out to sea. Never did make it to Wake.
They only make special trips to Iwo now for the men who fought there. Wake and Midway are sea-bird sanctuaries and emergency landing strips for jetliners that have engine trouble over the Pacific. You need a permit from the US department of the Interior to go there and study the birds.
The scary place to me was Chuk (Truk) There are probably 100,000 tons of unexploded ordinance in the bottom of the lagoon. You can snorkel there and see the sunken ships. I have no idea what the chances are of all the stuff exploding is but I wouldn’t want to be on the island if it does.
The street I live on here on Guam is what some of the locals call the “Way of the Spirits” supposedly the ghost of dead Japanese and American solders along with locals killed in the battle for the island walk at night. I’ve never seen or felt a ghostly presence here though I did find about 5 or 6 pounds of 6.5X50 Arisaka rifle ammunition when digging a vegetable plot. Construction crews here still occasionally find unexploded ordinance.
