We can kill multiple bucks in my state. The heaviest buck I ever killed was one that I passed on several times during the season and finally shot on the last day. My butcher said he was the biggest (weight) local deer he had ever butchered. I had been hoping for a bigger rack was the reason I had passed on him, but then decided I wanted his butt in the freezer.

I hunt several places, including my own place. I pass on small bucks at the owners request on his land when I hunt there and usually take several does before the rut.
My own place is only a small parcel of land surrounded by heavily hunted private and public land. The only time I pass on a small buck on my own land is toward the very last of the season.

I measure success by the amount of fun I have while I fill my freezer. All that said, I pass on a lot of bucks during the course of a hunting season but don't mind taking one here and there.
