i have seen deer use horse/cow trails before, and some areas where they just cross them. fresh rub is a good sign.
check the tracks and see which direction the deer are moving. maybe you can find a good choke point with maybe a better shot and/or better cover.
some property's are like a maze of deer trails, with one way in and 1 way out (per se), so sittin on those ends of the trails will help.
sometimes a road or dam, body of water or even trees laid down can make a funnel.
a good climber might come in handy as well, just sitting still high up letting yer scent blow over them.
