I'm in Waldorf, northern Charles County. Depending on traffic, it's between 30 and 45 minutes to the DC line (US 301 to MD 5); about 30 from VA (down US 301).Welcome SnowBear! I'm originally from Potomac, Maryland.
By the way, how does one live 30-45 minutes south of DC and still live in Maryland? Sounds like you would be well into Virginia.
