When I got a Muzzy cow elk tag last year, the Department sent me a map of the area's that had over grazing on. I would take sometime and look around those areas. Do a search on here for the Margaret Unit.....there are a few threads that have info also. But, beware.....it has change since 2007. Land has been sold off and trespassing signs posted.
a hint I was given was hunt around the river and to seemed to be a good one for me.
Good luck.
