Boyd appears to have missed some towns, for example Middletown in Frederick County is among the Post Offices, but no businesses are listed. In addition, there are some unexpected results. Many more businesses are listed in Rohrersville in Washington County than Rockville in Montgomery County. Accident, Bloomington, Deer Park, Grantsville, Oakland in Garrett all have businesses included. Germantown, Gaithersburg, and other towns in Montgomery County are not found.
