I was going to suggest a pre class meeting somewhere. Lake Rawling (the most likely spot for the class) or Roleville Quarry. The water (30-50 ft vis) and camping (2 dayer?) is a lot better at LR but it is about 2 hrs north of Raleigh on I85, Rolesville is 45 min north of Raleigh but vis is 20 on a GOOD day.
