Worknem and Russell,
I'm a member at the Gustine, our siren is activated electrically these days, but sound is still the same!
Russell, thanks for the note on the Gustine siren. We pride ourselves on getting it right.
Our closed zone does hold a HELL of a lot of ducks, it's really a nice feature and important to our success. We had a really impressive year this past season and we hope to keep it up. On slow afternoons its fun to sit in one of the blinds close to the closed zone and pick off the ducks as they work around the edges. Always good for a limit!
Take care
