This museum is a quirky labor of love. It is comprised of old photos and memorabilia stored in 4 forty foot containers (very retro) and dozens of old vehicles stored outside in the jungle. The museum was started in 1977 by a retired Marine, John Gerber. John had a passion for the Marines and for telling the story of their liberation of the island. John died a few years ago, but the museum is now run by friends. The entrance fee is by donation. Plan on about one hour to explore. I definitely think it is worth your time to visit while on Guam!
