Rich;
The rocks can be a bit slippery so definatly felt. I'd add a 5 wt to the quiver and a short (7') rod. A member (Stream) is in the Cherokee area and has been a big help with information on our trip. He comes in the Chat Room often around 8 pm CDT and weve been exchanging info.
Also there is a fly fishing contest the week end of Trout Fest, be a good weekend to go up in the park.
