Google search for Market at Grelen and google map will lead you there. It is a large facility hosting weddings and selling plants and home grown jelly. Its about 90 minutes from Manassas, VA. Its better to take a GPS like Garmin as cell phones are very spotty for the last few miles. The directions are not updated, at one spot the road is closed but you'll need to continue straight rather than turning into that closed road which is not possible anyway. Also, getting out of that place at night after a ceremony can be tricky. Remember how you came.
