Up to this point, I've only gotten one, but have called up a couple others at the wrong time; just playing with the call or all I had at the time was the .22. One thing seems to hold true, at least here in Indiana, they are where you are and will readily come to a mouth call or they are just not in the vicinity. I haven't worried about scent due to I always hunt so that I'm downwind and stay well hidden and very still. Here we have enough cover that camoflage isn't usually needed as long as you hold still. These are the methods that some of my co-workers and the local farmers have used for years. There is also a group that uses dogs, but the hunt can stream accross two or three different counties and you would need a four wheel drive truck. I haven't tried that--they are telling me also, that the coming winter months are the best time of year due to the coyotes are hungrier and more willing to come to a call-------John
