I've hunted all of those areas and you'll find elk in all three areas. The Wyoming range is some nasty steep country: Make sure your body is up to it. Plenty of people bow hunting in that areas. I hunted the Snowies for years. Its been awhile, but there were plenty of people up there as well. The Sierra Madres I only hunted once and would love to again. It is some remarkable country. The Big Horns had substantially less hunters than any other place I've hunted during the bow hunt. Let me know what you choose and I will recommend some areas.
