I've shot does on opening day a couple times when I knew my hunting time that season was going to be limited and I wanted to make sure I put meat in the freezer.
Normally I'll hold off filling a doe tag until later in the season, or wait until muzzleloader season. There's been a few times when I waited too long and due to bad weather, bad hunting, or having to change my plans I've ended up with an unfilled tag!
