reb8600, What you are quoting is from "Hunting Information" on their website, not the actual regs. I too saw that, but looked deeper and read the actual regs, and they contained the following quote:
Reg 002 - TIME & METHODS
"M. Calling or attempting to call or attract wildlife with electronic calls is prohibited. SCRWD personnel shall be exempt from this regulation when in the performance of their official duties. (Changed back to no electronic calls because that is what is stated in the Ordinance 76-1)."
That's why I checked further, because I got conflicting information from their website, but I think that if they would honor one or the other statement, it would probably be the actual regs vs. just a mention under "Hunting Information". In any event I did specifically ask about predators, because I was hunting them as well as javelinas, so there was no confusion there. I just checked on their website, and when you click on "Regulations", nothing appears. I pulled what I posted above from the PDF of their 2009 regs I downloaded and saved prior to my hunt. I could send them to you via email, but I don't know how to post the whole file here.
