My husband wants to take our 12 year old son to the Detroit Autoshow next week. He is a car FREAK and is also a supplier so he can get into the show before it opens to the public on Saturday. I can either stay home with my 9 year old son (who could care less about the autoshow) and possibly take a road trip to Chicago. Or go with them to Detroit. Anyone from that area that can tell me what/where the shopping is like? And should I go?
