This puzzles me, as I lost one of my tickets a few months ago, and had to go through the trouble of replacing it, etc. Even when you're issued a paper ticket nowadays, why does the physical ticket matter anymore -- it's not like it's transferable? Isn't it just a printout of a record that is electronic? What makes it different?

Also, curious: does anyone still use the duplicate red carbon ticket stock in this day? I don't think I've seen that for years now!
