I grew up with real trees, but I've come to feel like it's not such a swell idea to cut down a tree (whether they grow in a "harvest" or not), put it up in my house for a few weeks, then toss it in the trash. The whole thing just reeks of typical US wastefullness to me.
I don't really do any x-mas decorations at all, actually... again, it's that mentality of owning and having to store a bunch of crap that only gets taken out once a year. What's the point?
Of course, I live in an apartment w/ limited storage space and a cat who would destroy any out-of-the-ordinary adornments to the palce... perhaps I'll change my tune if I ever own a house.... not about the tree, though.
