[/quote] I go to school in San Antonio, so I'm near Aquarena springs. Apparently that has good viz but I have yet to go there. I dive in the wonderful mudhole of Windy Point at Lake Travis mostly. (countdown to Roatan...17 days!)[/quote]
Woohoo! Windy Point was where I was PADI OW certified back in mid 80s. The underwater visability sucked then too! I lived in San Marcos back then- the river rocked for shallow diving- especially after a big event weekend- get all kinds of goodies (watches, rings, sunglasses, even found cash on the bottom!) The Comal River in New Braunfuls is a bit closer to you living in San Antonio - really nice shallow diving there too!
