I can't speak for hunters in other areas. But I know my areas well which is northcentral 2G and southcentral 3A. I see what's growing, what's not growing, deer numbers, hunter numbers and such. I know what I've seen when the herd was high and I know what I see with the herd in single digits. I know what the neighbors and hunters observe.
BBs data pretty much matches what the overwhelming majority of folks in my area are seeing and experiencing.
