Where I hunt it's unlimited does, so I take 4 or 5 a season whenever they present themselves without there being a chance of spooking a buck. Some stands I'll never shoot a doe, but if I don't plan to be back there that year, I'll shoot a doe late in the morning when I'm ready to get down. I'm focused on bucks most of the time, but every now and then, maybe a couple times a year, I'll go where I know I can see a doe, just to have some action, and take a shot.
To each his own.
