Bull Run Quarry
This place is located near Manassas. Since everyone comes from different directions, I'm just putting in directions from Rte. 66.
Take Rte. 66 to Rte 234 North. Cross over Rte
29. Go about 2.5 miles and turn right onto Gum Spring Rd (rte 659).
Look for Luck Stone Quarry on your right - turn in there.
