I get down on the ground every chance I get. I'm only in the stand if I'm sure my chances are good, or the ground is too loud to walk on. Go with what your gut tells you. There aren't many things that will make hunting more enjoyable than trusting you instincts and overcoming your boundaries. You have to pay even more attention to the wind and try to keep the sun in your face if possible. Take your time and use a squirrel or turkey call to justify your noises. Keep a pair of thick wool socks in your pack that have silicone on the bottoms and up the sides. They are great for moving quietly. Good luck and have fun.
