I hunt them alot, and have hunted them in both Albany Tx and on my place in nebraska, tips, well
first be covered up, head to toe, sit still and stay at a stand for 20-30 mins, the sneak in, keep the wind in your face, and also, watch for cats, bobcats, they can sneak up even better then yotes. Personally i use my turkey hunting leaf-a-flage suit, because it breaks up the outline of human uber well, will staying under 100 bucks! Also, and if you get into the sport of yote hunting, you will want to invest in a foxpro, used or new, they work wonders!
Also, for hand calls, you cant go wrong with the "tally-ho" as well as the new split reed yellow "psycho tweety" both calls are around 10 bucks after tax from cabelas. and work great for the amature to the pro, they make a good sound, even if your not used to blowing calls at all. GREAT RASPY distress and the spycho tweety makes a awsome HIGH pitch witch really drives em wild for miles!
