Hey Tone,
I know it will have to be CSSP for me. Bill is working on his DM and that's where he works with the OW students. Also, it is the closest place for us. Athens is quite a ways further out - not that we won't do that again eventually. However; I don't know about diving in that water...with blonde hair....I've heard that the chemicals they put in the water have turned some people's hair green. I'll have to check that out further before diving there again. LOL....
As for PK - I will NEVER dive there again. The vis was terrible every time I've ever been, the ramp very very slick and the diving area way too crowded for me. I don't like a class of students "raining" down on top of me.
I know that there are a lot of people who dive both Athens and PK and enjoy both - but as for me - I want a little more open space and clearer water. Granted, CSSP's vis is down some right now due to the algae bloom but it is still clearer than any other place around so if I have to dive a lake....it's the one I'd choose even if Bill wasn't doing DM activities there. I think we will be there on Saturday.
Hope you have a good dive weekend wherever you choose. Sounds like there will be people at both Athens and CSSP so you shouldn't have any trouble finding a buddy. Let me know where you decide to go.
