So, I was on google maps doing some Virtual Hawaiian Siren Hunting. I used the “Thunderbolts Still In Existence” map to find a thunderbolt next to what seems to be an old civil defense bunker. Crazy thing, it’s most likely still active. The cords are 21.3949888,-157.9093565 if you’re interested. Another one is found next to another bunker at 21.29546531593676, -157.79048075763677. Are these actually bunkers, though?
I think they are active. Those might be bunkers. Imagine running to the bunker with the bolt all fired up.
