I have not seen a fawn with spots in quite a while during the season. I probably wouldn't shoot it if it did have spots. I'm soft I guess. Where I hunt we have ample bag limits, so whether I take it or not...really isn't dependant on that, I wouldn't be "wasting" a tag. I would NOT shoot a button buck. I have shot plenty of doe fawns over the years, and will probably shoot more. It really depends on my attitude at that particular time. Sometimes I just don't feel like fooling with them, so they walk. Good eating and easy dragging for sure
