Same thing happened to me in Montana, I believe it was 1975. Spent 5 days scouting and located 2 boars. On opening morning, a good friend rode 6 hours to tell me the season was cancelled due to a lawsuit. I hung around for 5 more days, hoping that the season might be reinstated, but no luck. Montana did finally refund my tag money. I hunted muledeer for four years in the Scapegoat and there was never a time I didn't see at least one grizzly. I hear now that there are way more.
