Not quite sure what type of deer/buck your looking for but if it's just meat then the closer to agriculture the better your odd's. Big o'l bucks will be both in the thick stuff and can be up high, but the closer to the rut, the closer to the does which will be near easy feed, cover which is farmland.
I see some nice bucks in the summer at my place which is at 3600ft and some does, but the deer get thicker the lower i go..
