Park # 277 Monocacy Natiional Battlefield, Frederick Maryland, plus two stops for Journey Through Hollowed Ground

I knew I needed to get to Frederick Maryland, so I could knock off park #277, Monocacy National Battlefield.  I missed it on the trip last summer, so I was able to pick it up. 

There were three stamps here, one site stamp, and a Journey Through Hollowed Ground One and a Civil War one as well.  Also got a pin and a hiking medallion for here. 

Then, I ran downtown to the Frederick Visitor's Center, and got a Journey Through Hollowed Ground Stamp there. 

Then, a few more blocks downtown and got another Journey Through Hollowed Ground Stamp and a Clara Barton Stamp at the National Museum of Civil War Medicine. Also got a pin for here.
