Is there anything to do in North Carolina?
You've got skiing in the mountains in the western part of the state (in winter) and you've got beaches on the east coast (Outer Banks) in the summer. It's a big state, you gotta be more specific.
There is a ton of stuff to do in NC, just depends on what part you are in. For general ideas you can check the following... http://www.visitnc.com/journeys
Try snow boarding, snow fights, snow men, skiing , the possibilities are endless.
