Personally I'd prefer the Dec 1-15th hunt.
I like late season patterns because if I focus on food, I've got a pretty good shot at doing some damage. Depending on when your rut is, I've also found that there can still be some late chasing in early Dec.
I've only hunted one state with standing corn and this was only once, so take this with a grain of salt.
But I found the deer were bedding in the corn during the day and then moving out of it at night. So I don't know how active it'll be in those river bottoms during Oct.
I'm saving my CO points to hunt WT. I don't believe it's as sought after as mule deer, so I am hoping to find a cool area with some mature WT.
