I'm glad you mentioned this K-girl, but not for the reason you might think. Although that looks like it's a beautiful display, you reminded me of one I want to be sure and get to when we are visiting our kids in OH at Christmas. General Electric's Nela Park is the company's worldwide headquarters. Every Christmas they light over 1/2 million lights along the drive through their property. Although it's nowhere near as large as the James Island one, we'll be able to take our kids after talking about it for years. I think THIS will be the year. It will be nice to share with the kids, since my own parents used to take a ride through there every Christmas season when I was a kid.
I think if I have to decide where to spend our money, we'd rather spend for the carriage ride and take the kids on the free light display. BUT you made me remember it before
we got to OH!
