I always had a real Christmas tree when I was married...but always felt bad for the waste of cutting down a perfectly good tree. Now I am divorced, and got a fake one...I love it because you can re-adjust the braches to accomidate an ornament that isn't fitting too well!!!
I have to have a fake one because if my sons allergies. He was always sick at Christmas time when he was little. Once I found out it was the real tree making him sick I stopped getting real ones. I do miss the smell though.
