Tireman, depends on what type of hunting you're going to be doing in Wyoming.

I would highly recommend camouflage when bow hunting, but rife season, you can wear anything you want as long as you're blaze'n orange!

Hunting Elk during rifle season, this fall, I will spending a week out.

I've never worn camo when hunting elk. I hunt in the muzzleloader season, which means I have to get almost (though, not quite) as close as bow hunters, but it also means I am required to wear blaze orange (this is in Colorado, I'm not certain but would guess the rules are similar in WY).

When hunting elk, just like when hunting deer, wind direction and the noise you make are WAAAAY more important than the color of your clothes.

Thanks for the information, I was hoping not to spend a large amount of cash on camo clothing.

I've only hunted modern rifle and have never used camo here in CO.
