Where do I hunt?
 

You hunt the areas on your land that the deer are using, look for sign and the fresher the better.

You hunt where the deer are. They will tell you the areas they use with trails. Try to find a spot where more than one trail trail intersect.

also make sure there isn't any safety issue's with shooting and safe back drops
8 acres isn';t a lot of land in the big picture, a rifle bullet can travel wall past it!
its impossible for us to tell you where to hunt on your land , as we are not there to see it?

best suggestions for a PLACE to hunt on your property will; be where it is SAFE to do so, and where deer are in shooting/legal hunting hours, and that you can get into and out of without being seen!

a LOT of times having a tree stand helps in many ways, , 1 gets you out of line of sight (SOME WHAT over the yrs deer have learned to look up) 2 it will help at times make shooting a LITTLE safer as it has you aiming downwards some what!
3 gives you an advantage at times on being able to see farther, giving you more time to get ready when deer are coming your way!
but like any hunting tool, you need to be safe in using them!

See if you can pinch them coming and or going from that corn field

deer usually dont bed down where they feed, so you might look to see where they are traveling. to and from the feeding and bedding area.you will want to set up between those two areas.

find where they feed & find the bedding area & & learn the wind direction &you're do good. don't let them wind you . try using a blind or treestand

Like the guys said either feeding or on the way from food to bed (mornings) or from bed to food (evenings). I've never had much luck trying to sneak up on a sleeping Deer, they usually have a back way out and sleep with one eye open. But you can walk likely places, brush or a hedgerow, and spot the grass or weeds matted down. Just don't get too close and spook them off with your smell, I usually figure thirty yards is close enough. When I scout a bedding area I usually wait a few days before I show up in the area again. You don't want to spook them off their routine.
Always look behind what you are shooting at. I get tunnel vision and I imagine other people do also. I have to force myself to look behind what I'm shooting at, the bullet can go right on through a Deer. I got shocked out of my complacency early one evening when I scoped a nice Buck, he took another step and I was looking right at some guys TV screen through some brush and trees a couple of hundred yards down the hill. I'm really glad I didn't pull the trigger.

You might also consider asking the cornfield owner for permission to hunt. Worst he can do is say no and you're back where you started. If he says no, as long as he's not letting anybody else hunt the cornfield, you still have a good setup cause deer will come back through your property to bed.
