A good friend just killed a big male coyote out here (about 55#) that came in to a grunt call and rattling antlers. He'd played that game before. Last year, the same buddy killed a large female (45#) that came to a grunt call and a doe-in-estrous bleat sequence. Size matters, and the bigger Eastern coyotes don't really worry too much about being outnumbered.
America needs to understand that our troops are not 'disposable'. Each represents a family; Fathers, Mothers, Sons, Daughters, Cousins, Uncles, Aunts... Our Citizens are our most valuable treasure; we waste far too many.
