Camo, in general, is over the top. Not saying it can't help but it's more about the gazillion patterns out there. 100% marketing. Personally the only reason I have camo cloths is so I don't get my work clothes mixed up with my hunting clothes. Fences, briars and blood take their toll. But I'm perfectly happy wearing brown duck pants and whatever natural tone coat I have handy.
In general just pic something close to the same tone as your area. Not the dark bark imitations intended for tree hunters, nothing really light either. No critter out west is gonna give too hoots if you're wearing a marsh grass pattern while sitting next to a sage bush.
