Not if you take the right precautions. Mask your scent as much as possible, always approach with wind in your face if possible, keep as quiet as possible, and once in place (find good cover), keep movement and noise to a minimum. I have hunted from the ground twice this year and lost both because: 1. a curious buck snuck up behind my ground blind the first time; and 2. a turkey walked to within 3 feet of me the second.

Good Luck.
