Favorites? Hmmm.... tough call. I like the category idea. Here's my 2 cents.
Best cache greater than 3 miles from parking: I'm not sure how far the whole walk is, but Myotis' Olin Nature caches were a lot of fun.
Urban Park: Moving Cache in Forest Park--I haven't done many caches in city parks.
County Park: Eddie's Money, Choices, River View
Puzzle Cache: ST8--Willmore Park, Choices, Zip (code) to the Grotto, (I'm still looking forward to Daryl and Daryl, which may get my vote for this category)
Micro: Reeds Spring Mill Micro Cache--the best use of a micro I've seen.
Cache with a View--Red Bluff Cache, Aggets-Part Deux
Hardest--Some Disassembly Required (extra difficult due to the spiders)
Kid Friendly: Speedway Lap 2 (great little park)
Most Unusual: Watchtower 3, and Yes, He Would
I can't limit myself to one best cache, but my nominees are:
Xtreme Shut-in
Xtreme 11 Point
Red Bluff
Daggett Hollow
Titus Hollow
Royal Pain
Surprise! (Turner Mill Spring)
Looking forward to seeing other's votes.
