I think your comments exactly reflect the purpose of this thread.  What does your kit look like and how does it match terrain.  For instance, I really don't need a seep straw here in the south east- so it's not in my kit.  DEET is most definately in my kit, but not a snow shovel.  I would like to see the choices different people make for different conditions.
