The problem here is lots of caches or interesting ones.
For lots of caches HugoNaDie developed a great approach by mapping caches. He concentrated on areas that were densely cache populated. He would exhaust that area and drive to the next closest ignoring all caches in between. This will yield the maximum number of finds in the time you have to cache.
For sheer enjoyment of caches I recommend you look for caches by the following cachers. There are surely lots of others but these are quite inventive. You might see somethings you recognize.

May those who love us, love us. And those that don't love us, may God turn their hearts; and if he doesn't turn their hearts may he turn their ankle so we may know them by their limp.... An Old Gaelic Blessing
