Hi MB,
I dove Lake Rawlins for the first time on July 4th, nice place. I live about 2 hrs from there but my dive shop does club trips there about once a month. You can try what a person did the day we were up there. He walked up, introduced himself and ask if he could join us. We met a new friend and he got 4 dive buddies. Our dive club has a camping/dive trip planed to Lake Rawlins on the July 28/29. I am sure if you show up and introduce yourself you would be welcome. I would offer to meet you there but I will not be able to make that weekend. If you like, email me and I can get you to the club pres if you would like to contact him. You don't have to be a club member to join in. Also, how close are you to Fantasy Lake (Rolesville, NC- just north of Raleigh)? The conditions are not as good as Rawlins but it's 45 min from me, may could meet you there on fairy short notice some time?
