I love the Travel Channel!

The "Secrets of Las Vegas" was one of my all-time favorites.

As for DSCW, I think that's the channel that "Airport" is on. It's a BBC show, documentary, I kinda like it. It shows the adventures of different airport/airline personnel at LHR (I think). I hear there is a show called "Airline" that follows the startup of EasyJet, and I"m pretty sure that's on DSCW too. Someone correct me if I'm wrong...
