sharpshot has hit the nail on the head on this one. i have accidentally killed 2 this year while i thought i was filling my limit of two deer during muzzleloading season. it is almost impossible to tell that one has nubs on its dagum head i dont care how good ur eyes are man. yea after walking up on both of them i regretted it instantly. and one of them was with 5 other deer....so i dont think that a button being wtih other deer maters....it was jus tbad luck that i picked it out instead of a scrawny doe.
