Not a hard find, but fun! Take a moment to sit and take in a good book after you find the cache. It should be pretty shady most of the day. Also, don't over think this one - it probably is easier to find than you think, BUT the Library itself is NOT the cache! Plenty of swag. Fun cache for kids to try and find too.
