This is one cache in a series being placed in honour of the Dewey Decimal System. (You can take the girl out of the library, but you can't take the library out of the girl!) Each cache has a unique Dewey number, and a bit of an explanation about what you'll find if you visit that section of the library.
*Please note that they are not being released in numerical order.
In 529 you will find Chronology - Including days; intervals of time; calendars; western calendars; Christian calendars; calendar reform; horology.
So why I did I pick Chronology for this little cache? Because it was place on Feb 29th, a leap day! Maybe this particular interval of time in a western calendar will help you maintain a streak, fill a "caches hidden on" calendar, or just give you a little smile for getting outside and getting to say "I found it!"
Hidden next to a shared pathway for cyclists and walkers - please do NOT stop your car on Castle Downs Road to get this cache! There are safe places to stop nearby. Container is attached to the host, so please be gentle.
