We put up a real tree yesterday. The house smells like Christmas! Real trees are a bit messy with the pine needles dropping and I've been tempted to go fake. Just can't bring myself to do that, maybe someday.
I had an artificial tree many, many, years ago. It was about a foot and half tall, my mom sent it to me. At that time I was in the Navy, assigned to VXE-6, a Navy Antarctic Exploration squadron (50 years on the ice and then was decommissoned; the NY Air National Guard took over the mission)
That small tree did bring some comfort to my little room. That's the only time I've ever had a fake tree.
