You probably have done one of the best things to start ...Looked in and chimed on here at Cas City.
Many many many, wise folks here, in the
"been there, done that" expertise.
What part of Florida ? ...you can't turn into 'nother county without finding a SASS club , range or members of this posse or that posse'.
Every weekend , Sat. or Sun somewhere they are holding a match....
So, look up the ones close to your home base, call then go to a few matches .
Bet you'll find , familiar faces , as these guys travel all over the State.
