This is one cache in a series of 10* 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 theme, which is reflected in the Dewey number it has been given. I am not assigning cutter numbers or subject headings. ;)
*Please note that they are not being released in numerical order.
020 is the dewey code for library & information science. This has nothing to do with the cache or it's location, but everything to do with the series as a whole. :) This cache is in a small urban park outside a church and a little strip mall. It's just a pretty, mature neighbourhood with a lack of caches. Take some time to admire the amazing front yards that some people have created. :)
