7,000 acres to yourself? WOW. You are a lucky person. Guess I'd travel for a shot at 7,000 acres to myself also. OK so you have a week. That time of year is going to be pre-frost so be sure you know what poison ivy looks like, dead or alive. The dirt roads won't be frozen either, most of Smith county only has gravel to where houses are, if there isn't a house it's likely to be dirt only. So be ready to walk to the nearest gravel road and park there if necessary (when it rains). Print yourself out maps from mapquest overhead or google maps over head view and take those with you. Don't plan actual stand sites until you get there so you can plan around wind. Wind is the most important thing I can tell you to watch. Next summer call the landowner and see what field they have planted in what crop. The week before you leave call and see what hasn't been harvested yet. In general deer like the bean fields and milo and you'll likely encounter both. If it's CRP be sure to stay in the bottoms.
As long as the landowner isn't pounding the place with hunters you should have a good hunt. Right now the state of Kansas needs money bad and they are really issuing out of state tags freely, and the people who outfit and lease land are "making hay while the sun shines" so to speak and really pounding their land hard with probably more pressure than they should, or at least some are anyway, of course I have no idea who you are working with so don't know for sure in your case.
Good luck you should have a real nice hunt!
