Counter Culture Fest crucial additional information

I've just been told "Viva Vienna shuts down Church St. for their festival. To make their way around the festivities, the easiest way to get to Dominion from Route 123 is to turn on Lawyers Rd. and take a right on Ayr Hill Ave (about 1/4 mile down Lawyers). Stay on Ayr Hill until you come to the stop sign at Ayr Hill and Dominion. Turn left on Dominion and we are on the right--#316.
