It looks like FCPS has updated their web site (since the last time I checked, anyway) to indicate the middle and high schools that offer different foreign languages:

This seems more convenient to me than trying to find the Latin booth at some county-wide presentation.

Their primary “customers” are their students, and overall they do a fine job. You sound like a real PITA.
