Mary,
I should have looked up your profile to see where you live. But I didn't. So please, do tell.
If you're in the US, there are tons of inexpensive possibilities for you. Florida, Mexico, and the Bahamas.
When I first started diving I didn't know another diver. I went down to the Keys and the Bahamas and paid the divemasters $40.00 a dive to be my buddy.
Some people might think this was too much, but I still feel it was well worth it!
I even think they made me a better diver in some ways. Kinda like when I play tennis with a player that is better then me. I get my butt kicked, but I always feel I learned something.
Have fun. Glad to see you're getting back into it.
And, check out the dive tables again, there really is nothing hard about them. Believe me if I can do it anyone can. My major was geography and not math at all!
