GPS would seem to be the obvious answer. However the GPS units I have seen seem to tell you which town or city you are close to, not necessarily in. I invite comments from folks who have more positive experiences with GPS systems with regards to knowing precisely which county or city you are actually in.

In the mean time I suggest a good Virginia road map which has the county and city lines well drawn. Borders has two: Virginia State Road Atlas from ADC and Virginia Atlas & Gazetteer.

Of the two the Gazetteer has the better details about the county and city lines.
