You've never flown? You've never been to Europe? I promise you, if you do one thing in your life that you'll enjoy, it's a backpacking tour of Europe. Germany, Austria -- these are must-sees. Even Paris, I suppose, cliche that it may be. And of course Ireland, if CW has given you a taste, although I've never been to Ireland myself.
What's more extraordinary is that I seem to recall you saying that your next and last CW show of this tour would be Red Rocks. Couldn't stay away, yes?
Don't worry about flying. It's safe and fast. It's too bad that the U.S. lacks a great high-speed rail network, of the kind that exists in Europe, but air travel in the U.S. is the way to go.
