No DIY in Alaska for nonresidents...Nonresidents are required to hire a guide for sheep in Alaska.... However, many areas in AK are OTC... Alaska is probably the cheapest alternative available to most of us mere mortals..... Many dall , stone and bighorn hunts in Canada are OTC, but prices are very steep...

There is an open, OTC area in Montana, but access is difficult and success rates are quite low...The rest of the lower 48 requires drawing a tag, again with low odds of drawing... A friend of mine did the unlimited Montana area hunt a few years ago.. He's an experienced hunter and had done dall and stone sheep hunts and a goat hunt previously..
He packed in a LONG way...Saw quite a few hunters and even got a look at a ram, 2 or 3 ridges away...he said he wouldn't do it again..
