I have been to a a couple in the Burlington, NC area, and some of those players play some high stakes games in the Durham area (2-3 NL and 5-5 O/8 are the highest I have heard at least routinely). I would not be best person to give details, but just alerting you that they are there.
I have heard about some games in Raleigh, but just from the internet site
I am not sure how reliable it is.
One of the Durham games was robbed last month for several thousand dollars. Guy busted in with a 9mm, and took the kitty. Did not rob the players per se. Be careful and ask questions about security.
