Justin,

Interesting you asked that question! For the past several days, the landowner who allows me to hunt (and who's becoming a friend) has been combining his corn, and I've been on stand most of the time. About 10:30 a.m. yesterday, I got bored and walked out to him and told him I'd take him to the nearest little restaurant if he'd let me ride with him for a few passes. I thought it would be a pretty neat learning experience, and one not everyone gets to do. Of course he said "sure," and I hopped up in the cab.

He had one edge of the field cut to within about forty yards of a fencerow, and as we kept narrowing it down, we jumped up three does which were bedded in the corn. We had to get nearly on top of them before they got up, and they ran around like rabbits dodging beagles before they finally left the corn. It was super cool to watch from that high perch!

That afternoon, I got back in my stand and saw five different deer.
Oh. Also, when we came back from lunch, I walked a fencerow back to my stand which divided two cornfields -- including the one he had been combining in. That fencrow has been torn up with scrapes for a couple weeks, but, of course, mostly from nighttime activity. Or so I thought. As I walked back to the timber, I could tell a buck had worked them while we were gone. Fresh, fresh upturned dirt which was just starting to get crusted over from the sun and wind drying it out. They were definitely not in that shape when we left.

So... hope all that helps. Do combines scare deer? Not a bit.

Discipline -- not desire -- determines destiny.
