it's funny.. I read a story about that a few weeks ago, then I saw the commercial the other day. They could've done all that crap in the studio and saved alot of money. You'd never know where it was filmed unless you have eyes to catch the shot of main street that lasted .5 seconds.
btw, I visited CB this summer for the first time.. while it is scenically stunning... the town did nothing for me. Seemed fake and contrived.. as in shoving the Victorian theme down your throat. Of course, this was also after touring all the Colorado Ski/mining towns all summer.. so maybe I was just Victorian-ed out.
