Doing some quick MapQuesting if Starbkjus come from Reston it is about 102 miles to Westminister and 46 to Frederick. With Canawler coming from Wrightsville (York) it is 52 miles to Westminister and 76 to Frederick.

Based strickly on this it I would suggest trying to split the difference and go with Frederick. (Davedove be quite I know Bushwallers is a simple walk from your door.)

Even though I would go with the Irish theme of Bushwaller's there are a lot of alternatives in downtown Frederick I don't believe are available in Westminister.

I vote for July 14th at 6:30 P.M. at Bushwaller's in Frederick.
