I went! And it was awesome! Great night for it.
So we got into the area about 5:15 and were probably got in line about a mile from the start on Richardson Ave. We probably entered the display about 7:00. So it took almost 2 hours for us to go the 1 mile. Full car with wife and two kids. Wife graciously offered to drive when we got in the park. Kids were preoccupied by a movie in the back, but did occasionally ask what all the lights were for. Think we pulled back on to 65 at 8:00. So it takes about an hour to go through in addition to the waiting line.
Its kinda hard to understand it in the moment, but when you see the luminaries on the hill outside the VC and how many there are, and yet there are so many more, or when you turn south on the Old Hagerstown pike, back toward the VC and Dunkard Church, and stop and look - its just beautiful.
I tried to get a few pictures but the lighting was very difficult and you really need a tripod to capture it correctly. I may have a few of the Dunkard Church that I will have to download.
