Lots of times people stop seeing does because all the dumb ones have been shot.
does have certainly changed their behavior over the last 20 years. Before the doe/day limit I would see large groups of does traveling together, as many as 20+ at times, but not any longer, the biggest group you might see is 3 maybe 4. I believe our doe population is down from what it has been but I know they are a lot harder to hunt these days.
