Since you've been in Cal, I'd probably suggest you start with re-aquainting yourself with which end of the gun to hold! (lol) Sorry . . . couldn't resist.
Seriously, read every word on this fellows site:

It will get you started in all the good directions. Very helpful site. And just a lot of good info.
Enjoy Montana and all the outdoors!
