Exchanges means that if you run into another letterboxer you can imprint
your personal stamp into their log book and they stamp into your book.
This happens a lot at the gatherings. I have not been to a gathering
yet, but I have exchanged with a couple of other "boxers" that I have
met over the last year. It is great to have a letterboxing buddy in
the same state to go out hunting with. Yes that means you SeeJoy :^)
even if I do drag her all over the top of the Mt. lol
Hope this answers your question.

I've seen a few of you mention exchanges and I know that's the E in the
signature lines, but I'm not sure I understand what you exchange. Do
you
carve stamps ahead of time and keep them with you in case you run into
another letterboxer?
