Have you seen these signs? There are some like these in our local mall here. I've also seen them on billboards around. I find them completely comical. The ones in the mall are backlit from 10:00 am to 9:00 pm. The billboards? Well, they light those up all night too so people can see.
I just thought it was a bit hilarious (and hypocritical). Perhaps Disney has found a way to light up these signs without using energy? Deep thought for the day.
