Bill, Powell is one of the areas in Wyoming (and there aren't many) that have good, huntable #'s of phez. Lovell, Dever, Basin, Greybull and Powell all have state sections of land, WIA's and friendly landowners with birds. I drive up there pretty much every year. There are also huns and forest grouse. Sharptail too on the east side of the Bighorns. The waterfowling can be spectacular.
Pinedale is a long way from pheasant. What it lacks in that ot more than makes up with big game opprtunities. Elk, deer, and there are antelope everywhere. Trout fishing in that area is as good as anywhere in the country, although you probably need a drift boat because river access is difficult. PLUS- near pinedale is some of the best sage grouse hunting in the west. And hunting them is really fun. Big, open country where the dogs get their first taste of a wide open hunt. It really is a great time if it is not too warm out.
I believe you have to reside in Wyoming a year to be considered a "resident", and thus entitled to all the benefits (hunting and fishing) that come with residency.
PM me if you'd like. I'd be happy to share any info you need.
