I had the Entiat permit in '04, and when I talked to a biologist about it, he told me the deer migrate down November 1st, snow or no snow. The does go first but the bucks follow, since the rut is going on at that time. As far as what size to hold out for, as others have said, I personally wouldn't worry about what a buck might score. A young kid killed a buck in the Entiat in '04 that was a massive 3 point, with eye guards, very long tines, tall but not real wide. Great looking buck but I doubt it would score very high.
