Big Dog Dry Wash is a geologic feature found on many layouts of the National Capital Trackers O-gauge Modular Railroad Club.. Three main lines span the gully on wooden trestles. People are not sure if the wash gets its name from the adjacent Big Dog Tire Company, or vice-versa. It is a popular place for railfan photographers because of the frequency and variety of trains that pass through the area.
Photos were all taken during the recent show at the College Park, MD Aviation Museum, December 12-19, 2015.
