I live in NC and ride the Blue Ridge mountains several times a year. The site seeing is great, and the roads are great. There are also a lot of tourist attractions in the area. That way if you are gonna make a family vacation out of it your significant other and the children have some to do to entertain themselves. You can gamble on the Cheerokee reservation which is only a hop skip and jump from deal's gap. There is also rafting, fishing, canoeing, hiking, old rail roads, crafts, the biltmore house, etc.
the other things to look at are accomodations and timing. If we want to stay near deals gap or in knoxville. I'ld recommend we check the dates. If there is a major event the hotel cost may be prohibitive for some, if we can find accommodations at all.
If we decide to meet there then let me know and i will try to get some information on housing and activity brochures together.
