Don't miss checking out the postings on the The Kentucky Piranha Patrol 's section. Being from Franklin, you are near enough to be considered a full member. They even encourage membership by Buckeyes. And I'm glad.
I've only been a member of the board for a couple of months, but almost all of the posts I've read have been friendly and helpful. Just like the divers I've met in person, since gaining my certification in February.
I've learned a lot from the folks on the board. There is a wealth of knowlege here to draw on. All you have to do is ask. As you've already found out! You're gonna enjoy the time spent here virtual diving, I'm sure.
Have a good time in Costa Rica, and tell us how it went when you get back.
New to the sport, and loving it...KYDan
