Does anyone have good still hunting or stalking tips to share?

I' ll be hunting this warm wet week of rut in Central Illinois probably on the ground.
I' m hunting a dry creekbed between 2 untilled corn fields with small woods on either end of the creedbed and nothing but tall grass and a couple of tiny trees in between.

I plan to hunt from the downwind side of the ditch, staying in the grass, wearing my homemade scent free guille suit and will bring a grunt tube to make tending calls.

Any suggestions or tips as I am normally sitting in a tree and not on the ground?
