need some tips on how to hunt on the ground using a bow without a blind
 

my plan is to sit on top of the hill behind trees/brushes looking down where i expect to see the deer to come in...

anymore tips would be great! thanks

try to gather a little brush to help hide yourself!

since you are hunting on the ground it is critical you hunt with the correct wind direction.

It will be tough without adding some brush cover. Step off a distance you would be comfortable shooting and try to find a tree you can sit or stand behind and add some brush for additional cover. Have a spot on either side of the trail so you can change according to the wind.

Listen to these guy's. They offer good advice.

Another thing I'd like to add is that you DO want to be seen by other hunters. You never know who else is out there with you, and other hunters will be on the lookout for the same telltale movements you’re putting out while you’re out there stalking.

Even if you’re on a few hundred acres of private land and no one else has permission to be there, you do NOT want to skip the orange gear. Not every hunter follows the rules, and not every hunter waits for an ethical shot (in this case, one where he knows for sure what he’s aiming for).

This is good advise as well as rh160kid's advice of watching the wind. Where are you hunting? what is the terrain like. is it all woods or is there open fields/food plots?

Sit with your back to the sun.

Wait till the deer passes you a bit before you draw.

I have taken most my deer from ground sits w/o a blind. Find a tree big enough to break your outline - wider then your shoulders. Make sure you rake the ground a few feet where your going to sit. I have spooked a few deer by not clearing a large enough area around me on the ground and accidently made some noise with branches/leaves when preparing for a shot. Setup on a semiangle where you can watch where you expect the deer, preferably angle your left shoulder facing the direction of where there going to be passing you from (if your right handed).

Make sure whether you are sitting on the ground or in a chair that you are in a comfortable position to draw and shoot your bow, you may want to practice that before hand.

It's very tough but make sure your concealed!
