RE: coyotes
A friend of mine - G kraatz - works for the state. They just finished up dropping rabies vaccination baits, and today should have finished up their helicopter war games.
They fly around in samll copters used for cattle herding and shoot coyotes and pigs. It is a state sponsord project that takes place on some of the biggest ranches in S. Texa. It is also done regulary when cows start dropping their calves. The yotes actually go in for the afterbirth. Last year he shot over 500 yotes and pigs in 10 working day. Thats no joke. He also uses cyinide bait , fence snares, and good ol 22.250.
