My wife an I have lived in Frederick county for more than 26 years, and we had never seen this bridge.
It is a beautiful stone bridge over the Monocacy River, and has a great deal of history. It was originally built in 1903, and rehabilitated in 1981. To bring people to it, we decided to place a cache here. As always, pix are appreciated. Please replace the cache upside down to keep the rain out.
