Christy and I recently had a chance for a quick getaway and we decided to visit Blowing Rock. It ended up being a great retreat for a few days. The NC mountains are wonderful and Blowing Rock was the perfect place to relax and unwind. It would be hard to stay more than a few days since you are somewhat limited with activities (unless you were camping, hiking, etc.). However, there are quite a few local restaurants/pubs, along with its close proximity to Boone, which can fill up a long weekend.
Here is a quick snapshot I took with my phone from our trip.
