I'm guessing you can tell a lot about someone by what inhabits the back of their car. At the moment I have the following in my trunk:
2 pairs of rubber boots
1 pair of gloves
4 reusable grocery bags that haven't seen the inside of a store in some time
makeshift first aid kit
emergency diaper and change of clothes for a toddler
I'm guessing that others might have a similarly mixed bag of goodies. What objects do you drive around town?
