The trip will begin in Boston and head to philidelphia on day 1. Days 2/3 will be spent in philidelphia and leaving late on day 3. From there, there's empty space/time. We would like to hit up my Vernon for a layover as well as 1 full day (2 nights) in the Williamsburgh, va area (Busch gardens ftw. Busch gardens will be day 7. This would put Mt Vernon on day 6. Wouldn't mind spending a night in Pittsburgh between 3 and 6, but have kids so a 6-hr drive isn't desired. Could use a spot or two in the middle to break up the trip. Thoughts of what to do in a rectangle between philidelphia, Pittsburgh, Williamsburg, va and a point south of Pittsburgh but west of Williamsburgh???
