BHA should be at the top of the list if public lands are a concern. When trying to decide in January what organizations to send my hard earned $25 to, their constant presence in keeping the public land debate front and center made certain that they were the first membership I paid for.
Check out www.backcountryhunters.org. I'm a national co-chair of Backcountry Hunters & Anglers and welcome you! That said, there a lot of great groups worthy of support. Also consider the BHA Rendezvous coming up in Missoula on April 1. Gonna be fun.
Along with BHA & RMEF, groups like Public Land & Water Access Association, Montana Wildlife Federation and their 24 affiliate clubs all fight for public land and field very good lobbyists in the capitol during the session to push back against attempts to privatize wildlife and steal access funding.
I couldn't help but notice there wasn't a plug for "Montana Sportsmen's Alliance" we formed after the 63 rd Montana legislative session. There were around 256 + bills that were either attacking sportsman, our wildlife, our heritage, or our department in adverse ways.
We are a hodge podge group of sportsman from around the state that work in the political arena of sportsman issues. Many times meeting with perspective candidates to see where they stand on these critical issues. They only people that testified more on these sportsman's issues, where paid lobbyists. We have both covered as we have a non profit group, as well as a Political Action Committee side.
