enjoy a treasure hunt and reading? then check out book crossing -- where you can "free your books." you read a book, register it on the site and leave it somewhere for someone else to find and enjoy. the site keeps up with (assuming people enter the info) where the book is left and when it's found. there's a whole lot of books registered waiting to be discovered.

i think it's an interesting concept, however i don't know that i'm going to start leaving my books lying around town any time soon. i'd have more fun finding a book i otherwise would never buy. |link via: snark spot|
