The Izaak Walton League's National Office (in Gaithersburg, Maryland) and Midwest Office (in St. Paul, Minnesota) have very sharp staff that are focused on conservation-policy related issues that affect us nationally and regionally. They keep us informed on issues (and when we as citizens / constituents should let our voices be heard) through email sign-ups and the national website.
An excellent way to stay informed and to act on issues of National and Regional importance in conservation, is to visit the National IWLA's Conservation Advocacy Center.
