You guys are missing the point. You need to park and shoot out of your truck next season. Since the deer apparently are "tuned in" to stand there like Prairie Dogs at the sight of the truck, just park it in your favorite spot and shoot out of the window. Nice, cozy, steady rest. Music to listen to in the mean time, no skeeters, no bugs, hot coffee if you brought some, heated when the sun comes up, not a human scent producer. Probably will be good results until you kill all of the dumb deer.
