I know I will probably get some grief, but based on my recent experience, Blowing Rock is not a very kid-friendly place in my opinion. It is a lovely town with many great stores and restaurants....for those 21+. We were traveling with friends and our 6 yr old and 3 mo old. We could not even get our stroller into most of the stores and those that we could we so crowded, we were not able to maneuver it around. My 6 yr old really enjoyed looking in some of the shops, but most were high-end and I was afreaid to take her in there. Additionally, the restaurant we ate at (I realize this may have been an isolated case) had only 1 high chair and stated on the door that strollers were not allowed.
Again, it's a nice town, but don't expect to spend a lot of time in town if you have kids.
