We are flying to Raleigh from Chicago the last week of July. I'd like to see Raleigh, Asheville and make a day trip to see my sister in Jonesborough, TN (close to Johnson City). Knowing that, what are your must sees for a family of 5 (10, 12 & 14)? We are wide open and happy to stay in a few places for 1-2 nights each. I'd love at least one stay on a lake during that week.
