I always re-pack my rolling case when I get home. Then I know I am ready to hit the road. You can always add something extra to a special trip, but all the basic (that we have all picked up extra of over the years), stuff is the same for all the trips. I have found that if I set back up as soon as I get home (OK - the next day is more like it), then things are still fresh as to anything extra I might need to add or things that I might need to replace.
