Well, I'm sorry browing, I beleive cascadedad is right that a coyote can not maintain that speed for more than a few miles. The reason I say this is I come from a family that has hunted coyotes longer than I'm been alive, with grey hounds. My dad had an airplane that we used for many years to follow the hunters on the ground and to assist in finding and keeping track of the coyotes!. Grey hounds are sprinters, and if they don't catch a coyote in about the first half mile, they aren't going to catch it, but in the years that I hunted with the grey hounds, I never saw a coyote that could out run more than 3 sets of grey hounds, because by the time the third set is released, the coyote is running out of gas!
No way a coyote can sprint for 30 minutes, even to save thier own life!
They outlawed the use of spotter airplanes in KS. many years ago!
