I don't know what it is, but Dally just loves Christmas lights. If we drive through neighborhoods filled with lots of lights, she's wide awake, looking out the window. (Which, if you know how Dally is in the car, that's the surprise. Normally she falls asleep the instant she curls up in her corner once we're out of the driveway.)
Because of this, we love taking the Stump Kids to the Kentucky Horse Park's Southern Lights. It's an annual tradition for Matt and I--we both love the Christmas spirit. And we cannot wait to add our child to the backseat next year so we take all three girls to see the lights.
