I drive a route truck and travel about 800 miles each week... i'm in a different area every day but every week my days I'm in the same area (monday hurlock, tuesday easton, wednesday ocean city, thursday chestertown, friday harbeson). Soooo for ME maintaining a cache in those areas would be EASY for ME.
As for defacing the phone book... around HERE>.... most phone books have been removed or destroyed for whatever reason... it is POSSIBLE.... the cache owner SUPPLIED the phone book.
My wife and I are foster parents... and there is a paralell to foster parenting and geocaching.... each child's case is different and specific to that child... in caching... each cache is specific to the cacher and the area...
