I'm new to both this site and the sport, and being that Missouri has few good places to dive that are within my reach... I'm afraid to say I'm in over my head (no pun intended). Any tips that you could give me... well I'd be thankful to say the least. St. Louis doesn't seem to have any organized free diving groups that I can find, so I've been on my own up until now, and reaching 2 minutes is still a struggle... so please help me figure out what I'm doind wrong!
