Because I am a Class 2 railroader (temporary structures only) I am able to build beautiful Christmas lay-outs. I collect stuff all year from yard sales, junk shops, etc.
Coca-Cola makes the best-quality items for their price, so they figure heavily into my lay-outs. I like Lego Christmas houses and have three of them. M&M items are cheap and glitzy, but I have a few good ones.
And then I have penguins (Yeah, I know--there are no penguins at the North Pole), polar bears, reindeer, Santas, snow globes, etc.
