Was caching in Arizona last month and actually got chased by a skunk. Had to leave the cache site with all the contents of the cache laying around, my backpack, water, GPSr, and everything in place to get away... little bugger gave a good chase. Got out of range within about 2 or 3 minutes, but sat on a rock and collected my thoughts and enjoyed the view while waiting about 30 minutes before returning to put everything back together and get my stuff and head to the next cache!
