My advise would be to locate ALL the clubs in the area.
CNC4x4
CTB
Triad
Core
VEX
BDB
etc..
Then talk to each of them. Plan to ride with each of them, at least once, twice if you can do it. Spend this whole year trying them out. Go camping, cook, eat, etc... Try ALL aspects of each club.
Your part will be to do your homework on each club. Research where their rides are and even what trails you may be best suited to. Possibly join any private mailing lists if your allowed to. Ask questions of the members. You will find you may like several.
I think you will find that most clubs are friendly and will welcome a new person in for them to test the waters.
Also you will find many clubs have small groups that ride outside of the normal 'scheduled' ride. Many clubs have groups that go to larger organized events or rides. So the fact is you will see most of the same people at many rides/events, even on the same day your their with 'your' club.
Lastly make sure any club you join is a member of the regional and national 4x4 associations. SFWDA - Souther Four Wheel Drive and UFWDA - United Four Wheel Drive
Personally, I'm a member of CTB, but I will ride/hangout/camp with anyone who's doing what I want to do. Rather than dump you to a web site for you to answer you own questions, feel free to PM me about CTB, while I'm not an expert, I will be happy to offer any advise I may have..
