RE: Ekalaka Montana
I think the genetics aren't there for a monster buck...
and the ratios seem to be out of whack, so if you can harvest a few does for each buck, that would only help.
I'm not sure pressure is the problem as much as the genetics...
If out that way stop in at the local taxidermists and ask what's good for the area...
But I think 150"+ would be pretty nice.
