Muleys are hard to pattern, unlike WT's and will stay in a certain area for a few days or weeks and then move on, sometimes they come back and other times they don't for a long time. The best time to hunt Muley bucks is during the rut. Bucks will travel along ways looking for receptive does. When the rut is hot, I like to get up high, where I can see a lot of country and glass. If you're patient and willing to stay at it, big bucks can be seen. Once spotted, you can try to stalk them. It works really well if you have a partner to keep their eye on the buck, while the other hunter stalks. You can communicate through hand signals, as to where he should go to get closer. Most of the time, muleys are in rough, broken country and you have to get into draws to stay out of their sight, so the partner really can help. One of my friends who live in KS, kills some big muleys in western KS.
Now in pappenz case, I am green and haven't hunted them in that kind of flat country. You might be able to pattern them.
What do you do with those empty nylon feed bags or dog & cat food bags? Can you say recycle? I use them for target practice for the youngsters. Take your empty shopping bags, stuff them into an empty nylon feed bag. You can also use old clothing or rags, (but put them in the bottom so it doesnt get top heavy). When your bag is full, fold the top over, punch some holes into the top and zip tie the top shut. Paint, draw, paste, or have the kids decorate their new target. Set it out 10 or 20...
