I put the tree up in the family room and decorate the door and front porch of the house with lights. I have two large lit snowflakes that I hang in the windows of the living room and dining room that face the street. These are all wired together and put on a timer so that it comes on at dusk and goes off around midnight.

We have the same set up, and we put our live tree in the family room (it's nice having the tree on at night with the fire going). Sometimes I put an artificial tree in the living room, but it's a hassle and only people driving by see it (and we live in a cup de sac, so no one really sees it). But we go overboard with decorating outside.
