Back in college, and for several years after, I rode a Yamaha Maxim 650. When I got married and started having kids, the wife begged me to get rid of the bike and not get another one until the kids are out of the house. As she put it, "Once the kids are grown you can kill yourself on the d****d thing if you want to and I won't care!" Four more years and our son will be out of high school and I will immediately be in the market for a Goldwing-style cruiser. Until then I just watch them go by and dream wistfully of that day.
