A bit of a different take on the "what's in your bag?" question. What kind of stuff do you take on a car-camping trip?
I grew up with a mother who can't go anywhere without her bedroom and kitchen - so she would pack most of their contents and bring them along. (All of the food we have for a specific meal, instead of just enough for the meal, etc.)
To give a full example of how bad it is, she has a 5-page checklist of stuff to bring. 12pt font, single spaced. 5 whole pages.
