I've got loads of different types of camouflage. I always buy it on sale or clearance. Cabelas bargain cave, walmart. Just bought a set of krypek on clearance from midway. I've got enough camouflage to last me the rest of my life!! Lol
As for out west, I wouldn't get too hung up on camo types. Same as any where else you would hunt. When I rifle hunt, I just wear my blue jeans, camo jacket and orange vest and a baseball cap.
