I lived for 6 months in the jungles of the Solomon Islands. San Christobel, Guaducanal, Makira, Savo and shortland Island.
Those places are full of WW2 aircraft. Japanese had large air harbours up there. Lots of Jap bombers and fighters sunk only metres off the shoreline. Lots of US fighters and a B17 in snorkelling depth of Guad (B17) and many of the northern Islands for the fighters. The Jungles themselves are loaded with munitions, US and Japanese Mortar and grenade caches, US Amphib vehicles, bunker systems, tanks etc etc. Savo strait is littered with sunken vessels. 2 of the Japanese Merchant marine ships are in only a few metres of water easily reached.
Ammo, dogtags, messkits, spoons, belts, chalkstone gravestones made by buddys. Its all there.
To imagine how these guys fought on places like Guaducanal, you have to go there to see the jungle itself. Those guys, on both sides did it very hard.
I have a couple of CD's worth of piccys laying around here somewhere. Gives a never ending appreciation for the hardship those troops, pilots and sailors faced.
