PAmaps18.zip contains numerous maps in the vicinity of
             CHESTER, NEWTON and NEast PA

             It was derived from PAmaps03 by adding lots of maps,
             compressing them in the new LINEFORMAT and adding all
             of the new WX WARNING circle labels.

             It also has all the street maps in the vicinity of the
             TIMONIUM fairgrounds just north of Baltimore for those
             who visit that hamfest.
