Do U have some GPS coordinatesof thes units?Don't get sucked into the old go for the waterholes thing...mulies can be along way from water, because that's where they are hunted by al the idiots!!! If U R hunting high desert I would replace a lot of walking with alot of sitting upas high as U can get and glassing every square inch of terrian U can see and then making a stalk...the worst thing U can do is go wandering aroun and spook all the game frmiles around...............U look at and under,behind and beside every sage bush U see, they can lay down in a open area with foot tall grass and dissaper...........................
