I got to go to a auto show like 15 years ago. It was a good experience. I think I might enter the contest. I would love to compare what I saw then with what I see this time around. I know my favorite part was the car of the future. Back then, it seemed like a dream to have an affordable green car. It is getting closer and closer everyday.
