If you can find some sagebrush on any public land you can potentially call coyotes there. Like the rest of us you just have to take a drive, find a spot you can hide your vehicle from view, exit vehicle as quietly as possible(don't slam doors), get a reasonable distance away from vehicle, and start doing the dying rabbit blues.
If the first spot doesn't produce then pack up and move a reasonable distance and setup again following the same routine again. Don't expect a coyote at every stand it just doesn't happen! Perseverance and patience is the name of the game. Good luck and remember sitting out there on stand beats sitting at work or school or on the couch watching the tube.
