I would also suggest using Trout Magnets, sold at LRO. My daughter's boy friend was camping with my sons and I last summer at Elkmont. He just couldn't get the fly rod thing so I pulled out an ultralight and bought some Trout Magnets in the green weenie color and bubble gum and gave to him. He caught 2 that day, one a nice in brown. Before the day was over both of my sons had gotten spinning gear out and gone to the river.
You can use these almost anywhere as far a water size is concerned.
