Kodiak Military History Museum
Kodiak Island, Alaska
What can you exhibit in a windowless underground bunker that was built to store hundreds of 260-pound artillery shells? A lot: vehicles, gas masks, typewriters, uniforms, walkie-talkies, old newspapers, a piece of a P-40 fighter's wing, a Japanese fire hydrant, and pretty much everything else that wasn't thrown away when this World War II shore battery was decommissioned.
This museum briefly made headlines in 2010 when a bar donated an old 1,263-pound aerial bomb -- named "Da Bomb" -- that turned out to contain live high explosives.
