Here are a couple more models that I have checked into Google Earth. If you have Google Earth already you can just type in "Frederick, MD " in the "Fly to" tab and take a look. Google Earth is free and can be downloaded here http://earth.google.com/download-earth.html

The Frederick Municipal Airport

The Carillion-Baker Park

Monocacy Battlefield Museum

(I have extra news about this one...but I can't reveal that yet.)
