Scott, I was wondering if you were Dry Suit certified. If not, DUI has their Dry Suit Rally at several locations throughout the year. Part of that involves Public Safety seminars for Public Safety Divers. There is one coming up April 14-15 at Beaver Lake in Arkansas. Day tickets (advance price) is $8.
Totally worth going for that price. Most dry suits rent for around $50 per day. For that measely $8 you get fitted, a brief education (as it`s geared for non dry suit divers), a test dive in a dry suit, a test diver hat, lunch (bbq), and the possibilty to make some new acquaintances.
Here`s a link to the dates if you`re interested in dropping in on one: http://www.dui-online.com/2007_rally.asp
