Abandoned but not Forgotten

This shot was taken at the top of the hill next to Makapuu beach in Hawaii. I was there looking for the famous Makapuu Light House when I ran into some abandoned military bunkers. These structures were built before World War II to provide the US military with sight on any potential enemy attack from that side of the island.  They were abandoned in the late 20s and are still standing (for the most part) there today.
