Visit Bronner's Christmas Wonderland website for a cool Google map that shows different light displays at individual houses around the world. Titled, "Christmas Lights in Your Neighborhood," the interactive map allows you to zoom in on individual light displays by clicking on star icons across the map. I initially thought that the map only encompassed North America, but a there are a few listings from England as well at the time of this post. You can post your own house display or a favorite in your area. You just need an address and a photo (of course ;) ).
There are not very many houses from Michigan just yet. I'll have see about posting a couple of the better displays that are around here.
