I finally made it! I've been preparing and training for this since January. Definitely my best cache find to date because of the experience. :) I went with a guided group and had a great time. We got lucky, as I think we were the only group of the day who got to see some clear skies up on the summit before the clouds rolled in. I, of course, told everyone in the group my plans for finding the cache on top and they were all interested to hear about geocaching. I've emailed the owner with details. TFTC!
