MM----sure I have hunted them both.
Island Park zone is a little more exciting with the occasional Grizzz sighting or fresh tracks and the wolves are around and ya hear 'em howl now and then... decent elk and a little to many dirt roads......for me.
Bear River zone-----no Grizzz.....no sign of wolves......but plenty of grazing permits for sheep and cattle........sometimes a hassle sometimes not a factor.
If ya throw your name in the hat for an Elk tag-----OTC---think about doing one of the overlap Bull Moose tags----pricey--- but odds are fairly decent in the 75,77,78 units.
Toss me a PM is you would like more intel.
