kflies, I used to live in downtown Boone. The Watauga is right outside your front door in Boone, but the DH has ended for the year. There is also some hatchery supported water that isn't worth the trouble in my opinion.
Your best bet is to pick up the parkway in blowing rock & head south west. You can be in prime Pisgah NF trout country in 30-45 minutes. My personal favorite was Lost Cove Creek. Its a steep little hike in, but it is C&R, fly only.
