I have a collection of camp stoves. Not only do I enjoy having them, but I have this idea that someday someone is going to want to know how one performs compared to another or how one works or how it feels to use. And I will be able to show/let them.

Other times I think of an interview Jay Leno did at an auto show. He said this hobby (collecting cars) was for people with more money than brains. Maybe that's me on a smaller scale. But I still like to take one off the shelf every once in a while and fire it up just because I can.
