Well this thread should be for the challenging/scary/adventurous/underwater/dragon-guarded caches I think, so that those looking for some serious action can know where it's at. I'm obviously biased in my first recommendation, and I think this only barely lives up to the supposed requirements, but I have to plug my own: Drum n Bass Arena. From the ammount of Bear-related incidents in this area that I've been hearing, I'll be packing my Taurus Tracker .44 magnum on future trips here just in case. Enjoy
