Group "like used" Items Together

Sometimes we put off things that we would actually do more frequently all because of an organizing dilemma. 

I have a friend who shared with me this summer that her family spends so much more time in the mountains ever since she put together a camping box a few years ago. It's just a simple plastic tub filled with things like matches, plates and forks, bug spray, etc. but she knows that she can load up the kids and the box and head up into the mountains for a few hours and have some fun with her family. It is a simple thing, yet often times we put everything back in "its place" after every trip instead of having the "place" be where we need it most often. If those supplies are all grouped together, it is much easier to get out and enjoy the family without all the stress of packing and unpacking each time. Which will actually lead to enjoying the outdoors with her family more. 

What else do you have packed and ready-to-go, or all stored in the same place so that you can find what you need easily?
