I'm a very optimistic guy, and these are three things I usually take with
me:
1) My cellphone
2) A collection of my favourite CDs
3) Warm clothing.

These things should be in my vanagon, but usually not:
1) Tools
2) A Bentley or Haynes book(Idont have any)
3) A Hand-winch and ropes(when I get stuck Off-road)
