Everyone knows about the Longwood Gardens Christmas Lights Display, but just down the road at the Herr's Factory in Oxford is a FREE display on the trees and factory.
The whole campus is lit up, offices, factory and all the trees and the grounds as well. It is a drive through experience, but a fun one.
After you have driven through there are plenty of places to enjoy dinner locally in Oxford and Nottingham, or a bit further away there is West Grove and Kennett Square. People come from Maryland, and all over to drive through and enjoy the display. No free chips, but a wonderful free light display.
