We have hunted 63 one year (2011 first year we hunted antelope at all) so am familiar with that area. Any ideas why unit 69, which is across the road, is not rated better in MRS? Not even deserving a "marginal" rating most years. Is it surrounded by a high fence, or what. Because of its location, bordered by good areas, seems like it must have some problems not obvious at first glance that affect it. Thanks for any info you can give.
