First off just sit in the brush. You will be making several set uPs in a day, so a blind would be a pain. Using two fellas is great. Many yotes hold up way out to 80 or 100 yrds before coming in. A decoy will help a lot. Use a couple of calling sequences over a 20 minute period. I wouldn't stay in one place much more then that. Use a critter or fawn call and wail on that thing so it sounds horrible and painful. Once a yote is coming in, do nothing more then some little squeeky calls unless they are far out there and not locked on your location. I don't know what kind of terrain you have, but your son could be in for a great time. Oh yeah, don't move except to draw.
