I too have great memories of riding on the back of my dads 74 Yamaha DT360 Enduro and later, his brand new 82 Nighthawk 650. We used to ride it to football practice and always took the long way home. When I was 18, we bought an 84 Shadow 1100 and took turns riding it and always hung out in the garage working on it. About 12 years later, I got another street bike, which prompted him to buy another street bike and we spent many days riding together. I dont think we would have spent nearly as much time together in the last few years of his life if it weren't for motorcycles. Now, My daughter and I have been riding together since she was 8. Shes 13 now.
