We went through a small phase as kids.
@sean : Have you taken the kids to the model railroad museum in San Diego?
Wouldn't surprise me if you didn't even know it was there - my Dad loved it more than us.

Unfortunately, you just missed their Friday fundraising event...
Beer and train lovers “hop” aboard this holiday season and combine some of your favorite things: Ales, rails, and ugly Christmas sweaters. Mark your calendars for Friday, December 11th from 7:00 pm to 9:00 pm and enjoy local craft brews from Julian Hard Cider, Societe Brewing, Nickel Co., and Intergalactic Brewing Company. Enjoy some delectable delights from The Grove Pastry and Blush Desserts. Gather your friends for the most “hop-n-ing” event by wearing the most abundantly adorned, cheesy and downright hideous holiday sweater to this year’s Ales & Rails event at the San Diego Model Railroad Museum. Plus you'll get a chance to win ugly Christmas sweater merchandise provided by The Tipsy Elves.
