I'd get after the Coyotes too. The mornings have been nice and cooler around here too and it has me thinking of Coyotes also. However with all the crops in the fields and the majority crop up here being Corn it makes things tough for calling Coyotes this time of the year.
Good luck on the hunt.
It is tough for calling coyotes in Ga anytime of year. We do not have open land here...this is all woodland. Coyotes in dense vegetation are tough critters to hunt. They will come in, you will never see them, and they will work their nose until they nail you. Also, just like in your area, they virtually never stop moving. I have been hunting them off and on for 25yrs and I figure that you have about 5 seconds to shoot, after a coyote shows himself.
These things combine to make a coyote in my area, that is called and killed...a trophy. But, it is fun...
