As has been stated, good and bad. Bad for the rut, in my experiance, rutting actionhas always been slower around standing corn (because they are spending time in it and you just dont see them)

after the rut....then it is good, deer will flock to it as a food source. Hunt the edges, and as mentioned, try a SLOW drive or two just before harvest.

Now if you have some experiance on the ground and are pretty stealthy....do some still hunting on a windy day. I have not done so in a corn fieldbut have seen results of people i know.
