I have also used bait piles, usually dead deer from the road, and have also been successful. Predicting a coyote is like me trying to predict my wife- but I love her to pieces /ubbthreads/images/graemlins/grinning-smiley-003.gif- so that is why I also set up a trail camera near the most obvious site. I have gotten nice pictures but have also seen when the coyotes came in to visit /ubbthreads/images/graemlins/grin.gif. This year from my camera at least one coyote was coming in every other night between 4 and 5 AM, at least while there was snow on the ground. But I also got nice pictures of hawks, one bald eagle, and numerous other critters. I have found that the entire deer in one spot is not necessary. I cut the deer into about 4 or 5 different sections /ubbthreads/images/graemlins/shocked.gif and put them out in many places. Wireing them to a tree will keep the meat in one spot. Snow, obviously will show tracks without taking down the camera.
