My brother and I generally go up in May (he's in Chicago, I'm northeast TN) to catch the tail end of the caddis hatch. We stay at this campground and meander around looking for water. There is a small store just across the stream from the campground (swinging foot bridge) where you can pick up flies, drinks, etc. and pay for the camping. Firewood at the house next door. Owners are very friendly and you can pick up some real maple syrup from the local Amish. Richland Center to the south has a WalMart and Westby to the north has an IGA type grocery store.
PM me if you need more info
