On Sunday, I had the rare opportunity to test out a wormhole that would lead me back in time to 1975. Upon my successful arrival, I visited an AMC dealer where the owner gave me a dirty, puzzled look for my strange clothing and Martian camera. Since I had the money, I decided to buy a car. I was disappointed when I learned that I couldn't take my gently used Rambler American hardtop home with me when I made the time jump.
