Sourdough is right. Working with your local Advisory Committee is more likely to be successful. What's real good is to bring a number of friends too - talk it over with everybody and take time to listen to other opinions. Often Fish and Game staff is there to explain the department's view point as well as to present any data available. Really helps to get the full picture on the issues.
In my area there are a number of proposals from city based (mostly) anti hunters that fly in the face of what locals really want and have been working towards for a long time. For instance there are a number of proposals to make bear seasons or hunting more restrictive in places where bears are very abundant and a bother to locals. Some of the current seasons were just established in the last 10 years to give locals more opportunity to hunt bears in the accessible areas and time of year - and to moderate the predation on moose and caribou.
It can really help if a number of Advisory Committees agree on one approach or solution. Out here in Bristol Bay the leaders of several ACs know each other and stay in touch, coordinate efforts to be a stronger voice.
And you know folks, even tho I usually don't agree with anti hunters, they DO have a right to their opinions and deserve a fair hearing. If they get a fair hearing and even some considerations some times, they have less grounds for complaints. But if they don't even get to be heard then its understandable that they'll continue to try to get the legislature to do their bidding.
