Just got back from GSM, and I have to say Elkmont was one of the highlights, not only fishing, but a great place to explore. We were very successful using yellow caddis' above the cabins. These holes are really small, and you will probably only get one shot, or maybe if they're nice, a second shot. If you miss it, or no one's home move up to the next hole. It's amazing the size of the water that will hold fish, so don't be afraid to try any pool you find. A bow and arrow shot sometimes is the only way to get it in some of these spots, but if you've got a 8'+ rod you can try just dropping in a short tippet, just be quick. *Good Luck.
