I should have taken a picture of the entrance but they have not plowed or anything even down at the beginning of the Front Royal area before the guard/gate. They did not get get that much snow down here so did not even think to check. Was going to look at some of the "ice walls" where the water is coming out of the mountain along the roads.
I have been in the Caverns near Hummelstown and it was cool, may feel chilly right now. Never in Luray at this point.
