It's fun to be on vacation and go visit one of these. They're usually not in tourist areas and are likely to be in well established neighborhoods that a a different vibe than home. Also fun to read and come home with some random book that anchors you to that trip.

yeah! I've done some geocaching (or even just walking around exploring) while on my travels, and have very often encountered these "leave one, take one" type of free libraries along the way. It's really interesting to find different types of books depending on the area - the small town on an island of course has all these books on marine travel, sailing, that sort of stuff, for example. Nice way to get a little extra idea of the area and its culture, sometimes.
