first off welcome to the board,your set up sounds good but don't expect the fox to cross that open field.reds will very rearly cross an open field to responed to a distress call,grays on the other hand just might.they will most likly trot down the hedge row your sitting in.the only thing i don't like about your set up is the standing corn to your back.if the wind is blowing to the corn,your going to get busted long before you see anything.if the wind is blowing to the open field expect the fox to run along side the hedge row and at any where from 50 to 100 yards trot out into the open field trying to wind and see the sourse of the sound.then again they may fallow the hedge row right to you.always give fox some cover to get within shooting distance of you,a hedge row is perfect.if the wind is blowing with the hedge row,don't hunt there.if this is the only stand site you have set up,you need to set up many more.even if you sit each stand for 30 min or so,if you only have 1 or 2 stands your fox hunt will be short.its also good to rotate stands,try to not hunt the same location twice in a row.over hunting the same location only serves to educate the predators in that area.night hunting fox is alot of fun,enjoy and shoot straight.
