I might try to keep this one forever. Usually, I take my tree down and put it in the backyard for the winter. Neighborhood critters use it for shelter, and sometimes I will fill it with treats for the birds.
I won the neighborhood light contest again this year, although none of my neighbors know it's a contest. I left my outside holiday lights up longer than anyone else on the cul de sac, and the cross street. I'm thinking I have certainly won the "longest living tree still up" contest as well.
