I believe I went to WinterFest once, however I was very young. My mom did say some of the flats were open but most weren't due to the temperatures in the 40's and 50's.
I expect that noticeable signs of demolition will be seen around the beginning of Halloween Haunt. I will make sure to get shots of demolition from all around the city of Mason. I know one area that will be perfect.
Yeah, each ride has a backup generator that can power it for at least a few more trains if its a coaster that needs power for the brakes, or at least 1 cycle if its a flat ride.
