DAY 1: happens the last week of October, when the final cold front of the month moves through.
DAY 2: is usually during the first few days of November, when the first doe in your area comes into estrus and launches the forest into chaos.
DAY 3: is when several does are in estrus at the same time. It generally happens around November 7 in the Midwest.
DAY 4: is any day after the first three, when a hot doe passes your stand. The only way to take advantage of it is to be there when it happens. If your property is set up to maximize your chances, you may not have to sit for long.
