Fred opened Martha's a week or so ago. I'm new to Nashville, and dove Martha's on opening day, April 1. The average water temp was 50 deg, and hit 47 at the coldest. Brisk! Visibility was pretty decent, for a quarry (~25').
We'll be there this coming Saturday, April 15, if you want to join us. We roughly plan to practice bouyancy while task loaded (s-drills, shoot a bag, etc) on the first dive, if you're interested seeing/practicing that kind of thing. Basically, we'll probably stay put on that dive to get our diving legs back after the winter, working on whatever skills you want. On the second dive, we'll probably do some exploring of the attractions, like the u/w houses. It'll be a loose group of DIR & non-DIR divers, so everyone's welcome.
We'll probably get there around 10am or so. You can look for me. I'm a small guy (5' 9"), drive a black Audi, and have a TLS 350 with red overlay. Some say I bear an uncanny resemblance to my avatar, but I beg to differ :monkeydan
Best,
Mike
