Oh man, if you are coming from CO you are going to be disappointed.
Seriously, if you are going to be close to Blowing Rock/Boone it is probably worth a visit if you are itching to ride. Personally I would drive on up the road and hit Sugar or Beech. Crowds may be a tad worse than App., but the "resorts" are bigger. When I lived in Charlotte, App was 1.5 hrs and we would always drive the extra 30-45 minutes to hit Sugar or Beech.
