At the posted coordinates, search for part 1 of the cache, which is located outside of the library building and accessible at any time. You do not need to pry or force anything open.
Part 1 will give you the Dewey Decimal call number for the location of the cache inside the library.
The library has limited hours and part 2 will only be accessible when the library is open. Note: This building is in active use as a library. Please be quiet and respectful of the people who are here to read and work.
Current library hours are:
Monday - Thursday: 9:00 am – 8:00 pm
Friday: 9:00 am – 5:00 pm
Saturday: 12:00 pm – 5:00 pm
Sunday (September - April): 1:00 pm - 5:00 pm
(Visit http://fairfieldpubliclibrary.org/my-fpl/hours-and-holidays/ before coming down to confirm hours)
Find part 1 to get to part 2. High muggle/traffic area, so some stealth is required.
