Pre-Christmas Decorations?

It's a bit hard to tell in the picture but while going out to the Wone Branch for an institute class we observed this bush decorated with beer cans.  Actually the entire roadway leading to the house was decorated in this way.  I suppose it is a way to create some Christmas decorations a little early.  Maybe I can use this method of decoration when I get home to Gresham--minus the beer cans anyway.  How about my Coke Zero cans?
