I visited a tiny library at Mt. Charleston in Nevada and loved it. I got home that evening and did some online research and found all sorts of crazy libraries, my favorites being ones that moved or were somehow portable.
In Columbia there's a mobile library that's a guy on a donkey, there's a floating library on a lake, a mobile camel library in Mongolia, and in New York City there are people with libraries attached to a backpack. Crazy mobile liraries and just plain cool. I might bring this to a park, festival or just an open spot in the woods.
