BHA's structure is this: Each state that has a chapter which is formed of volunteers who decide what they will and will not work on. MT's chapter works on license allocation, forest planning, wildlife management (like shoulder seasons, etc). I don't know what Idaho's chapter is like, but I know several state chapter leaders who are actively engaged in state level wildlife management.
The national BHA organization works heavily on federal issues and actively lobbies congress on issues related to sportsmen, hunting, angling and public land management. They are a very effective and credible voice on the Hill for our issues. TRCP similarly works on policy at the federal and state level that effects wildlife management and wildlife habitat. They are growing and should have some new staff coming on in the Northern Rockies.
BHA doesn't sue, and their positions are nowhere close to the far left groups Pinecricker mentions.
& I like Rocky. He does some great work.
