RE: Entering a corn field...
Well...it looks like the best way to not get busted is to walk around the field, then go directly through the cornfield heading east to your stand. I don't know how big the field is, and it might be tough to do if to rows of corn are planted North/South. Walking against rows is nearly impossible for any distance.
I think the real question is, won't the deer bust you in your location with a West wind? If they bed in the swamp and woods, won't you be getting winded before they even leave their beds? Or have I read the diagram wrong? What is located directly east of your stand?
