Father / Son Boondoogle

My son had vacation this week, my daughter had school and my wife was in Europe. What to do with a 10-year old? Take him to California to spend some time with the grandparents. For some reason I couldn't find a direct flight from Boston to San Francisco so I had spend a night in Detroit on the way there... so we went to the Henry Ford Museum.. and along the way we somehow stumbled into Superlite Cars / RCR...
