I always try to tweak my Christmas trains every year. My grandfather called his layout a "Christmas Garden," a nice name for the tradition.
This year I went to Michaels craft store and bought a fake gingerbread house kit that is actually made out of foam board. The figures I used with it are the old Rudolf set sold about ten years ago. The string of lights on it are the little battery operated LED sets sold at Walmart.
The camper trailer I bought at a Goodwill thrift store on Route 202 in Chadds Ford, Pennsylvania (just above Wilmington, Delaware) for five bucks. They had dozens of them in stock (all brand new) so if you are in the vicinity check 'em out.
Merry Christmas to all!
