It's not often we can associate fun with a financial institution, but PNC has done just that with a holiday model train adventure. each year the company studies the inflation rate for all the items mentioned in the Twelve Days of Christmas, you know, turtle doves, french hens, maids a' milking and the like. As you ride their online train you'll be taken through a number of puzzles and games that express the results from that study. The impressive visuals alone make it worth the ride.
