Or if you're broke like me and you gave away your christmas tree to some poor loser last year, you won't have a problem cause you can't afford to get a new one!
For those environmentally concious people who are also concerned about putting out christmas lights and using electricity to power 'em, you are welcome to live vicariousely with my christmas lights ;-) BTW, they are wind-powered ... no, there's isn't a windmill on my property (I have been asked that question!), but you can sign up with Xcel Energy (and pay some extra $$$) so that your power comes from wind sources.
