For me it depends, each year I switch off having Christmas with my mom or dad. Since i live with my mom we have our Christmas here, and I'll have my model winter or w/e village set-up. My mom will have a Christmas tree and decorations up, and basicly my mom, grandma, and I just spend time with each other. We'll also watch "It's A Wonderful Life."
With my dad, on Christmas or not, we'll always go up to either North dakota or Colorado (this year Steamboat Springs, CO, which is in the Rockies.), and we'll celebrate with family up there.
