A rural location in northern Baltimore County, Maryland. The "Zone" is bordered by Carroll County to the west, Harford County to the east, York County, Pennsylvania to the north and the suburban sprall of Hunt Valley, Towson, Lutherville-Timonium etc. to the south.
The Hereford Zone is set apart from the remainder of Baltimore County due to it's rural setting and it's snow line. Anybody traveling Interstate 83 can attest to the snow line at Mt. Carmel Rd. where the snow magically stops to the south.

to tell someone to calm down and relax.
