Once upon a time there was a family. This family was into both sci-fi and adventure, and sometimes a meshing of the two. One year, this family went to Walt Disney World for Thanksgiving. They ate huge turkey drumsticks and wore matching pirate t-shirts that said, "Beatings will continue until morale improves" on the Pirates of the Caribbean ride. Two of the sons in this family decided to buy their father a gift while at Disney World. They bought him an Indiana Jones hat. It fit his interests and personality perfectly.
Years later, the father, who had been saving much of his life to buy a Corvette (he'd once owned a red Camaro) bought a Harley with his 'Vette savings. Well, his wife bought for him, for Mother's Day (odd, yes, but that's how this family is). He bought a smaller one, uncertain yet of his ability to comfortably control a larger bike. Many adventures ensued. A few years later, he came into a small sum of new money, and found another --bigger -- Harley, gently used, right in his price range. After thinking about this particular bike for a whole 24 hours, he bought it.
When he took pictures to send to his family (now spread across the country), his oldest son, one who had bought the hat for him, pointed out that the bike looked like the style Indiana Jones rode in the last (fourth) movie. Though the colors aren't the same, the style is quite similar.
A week after buying the newer bike, the man's (third) son and daughter-in-law came to visit. The daughter-in-law is a photographer, and the man has a sense of humor. He dressed up in his Indiana Jones hat and rustic brown leather jacket, put on his toughest face, and asked her if she would do a shoot with him and the bike, inspired by the snark of his oldest son.
