Depending on the gear you bring - Fantasy Lake is an option - simple, reasonably accessible, passable visibility. Three weeks ago vis was still good, but SB suggests it may be declining. SB and several others may also be able to link up with you to dive up at the PDRA quarry (Piedmont Diving asnd Rescue Association) near Yanceyville, which is probably 1 - 1.5 hours from Raleigh, is deeper, and better visibility (and cheaper). Where are you going to be based during the week? If you're in Durham (i.e. at Duke) or Chapel Hill (at UNC) then the PDRA facility is a good call. If you are strictly in Raleigh / Cary, then Fantasy is the better option. I wouldn't mind a PDRA trip on Tuesday afternoon / evening.I'll be arriving in the RDU area on the 29th and in the area through July 3.
