Thank you songdog for correcting the "theres no way they have permission" crap. Dont know if these guys have been out to central, or western ks but there is still a lot of large tracts of land where we run coyotes. And you would be surprised how many farmers just want the coyotes dead, and unless you can kill 20-30 coyotes a day calling, they just might opt for the coyote wagons to come in!! There are many exceptions and lots of farmers who have been burned by fence busters or livestock chasers but many still value the way.
And i for one hope this sport doesnt "die" out, just like i hope that the sport of calling coyotes or turkey hunting doesnt.
