I was the park Saturday the 30th, and saw no one milling around Lighting Rod at all. Mystery Mine also didn't open until 6:00 pm which made the lines for Wild Eagle, Firechaser, and Thunderhead long. We opted to get unlimited timesavers and rode all day.
It was The Great Pumpkin LumiNights opening weekend. I found the decorations quite nice and is a nice addition to the park for the fall.
