I've heard from others that as soon as the velvet comes off they stop their summer routine, which generally has them out in the more open areas so they don't damage their velvet, and head straight for the thick stuff as they no longer have to worry about tearing up the velvet. It does kind of make sense and does somewhat fall in line with what I have seen. This year I'm trying the first week of Sept. with a bow/xbow to hopefully catch them before they rub and move on.
