Bunkers of Alvira, Pennsylvania
Many years ago I heard of old bunkers from WWII located somewhere north of Harrisburg, Pennsylvania. Over the years I tried to find more info on them but always came up empty. Until I stumbled across an article last week which had an overview and directions to these bunkers! What else should I do with a day off but go explore the bunkers of Alvira, Pennsylvania.
More information on the bunkers of Alvira can be found over on Atlas Obscura.
