I got PADI certified back in highschool in 1996, I then took a college class at FSU and got Advanced Open Water NAUI certified in college back in 99 or so. Its been a few years since I've been diving, I was actually just having this conversation with a buddy of mine and we both agreed to take a refesher course somewhere before the summer gets here. I remember most of the basics, but you don't want to fuck up a dive table on a 100 foot dive :-)

Another good friend of mine got cave certified and dove many of the sink holes and got to help stage a drive into Wakulla Springs.. he has some bad ass videos.

Something about sweezing yourself and three tanks through a 3x2 hole 300 feet under water just does not sound right...
