If you click here you will see a house here in San Antonio that is decorated for Christmas all year long. If the link doesn't work, just google "Ed Clark's Christmas lights". It is quite a sight.
The legend is that his wife's favorite holiday was Christmas and when she died, he decided to keep the decor up all year long. He adds things to it each year.
I think this is one house we will miss on our driving tour of lights. Riverwalk and Alamo Heights, here we come!
