Seeing one of those cards above reminds me of the online survey I took the other day. I don't usually do surveys but I was bored and thought what the heck. Anyway, it asked if I traveled (yes) and while traveling I had I ever used public transportation (yes--some cities it works out). So that must have gotten me to the next part which was about whether I would use high speed rail. They asked the question all different ways (citing convenience, ticket cost, the environment, cost vs parking or renting a car, etc) I made sure I said no on every one of the questions. But you know if I was a dumb nut I'd probably thought it was a good idea based on how they asked the questions.
Now I'm glad I answered the stupid thing.
