I would stay away from any road that connects to a major highway. For years, every beginner gets the same idea and calls the exact same areas you describe. Plus being just outside of a major city with millions of people, you are going to run into far more frustrations than it is worth. IE; Bird hunters, atv riders, hikers, bikers or law enforcement checking on your "suspicious" vehicle. YOU NEED TO THINK OUTSIDE OF THE BOX.
Using Google maps, look for transition areas......the best definition for a transition area is a place where the terrain changes state. Like where a cotton field meets a creek.....Anyways there are lots of examples, the point is look for changing terrain. COYOTE FOOD IS NORMALLY LOCATED THROUGHOUT THESE SPOTS.
The coyotes will spend early morning and evening hours traveling through transition areas in search of food. Spend 15 to 30 minutes calling these areas using a distress sound to bring in a traveling coyote. (I can honestly say that I have called in a coyote with every distress sound on my Fox Pro) They all work or they wouldn't be there.
At about 9AM the coyotes have usually made it to bedding areas......look for brushy, thick areas or edges.
You have to carpet bomb the bedding areas, so you need to start these sets with something loud and alarming to wake them up. Coyote Vocals seem to do the trick in the middle of the day.......DO NOT OVER CALL AT THIS TIME!!!!
The idea is to wake them up, pizz them off and wait about ten minutes. If nothing shows up, drive one mile and do it again.
You would be surprised at how many doubles I call in doing this.
Good luck out there!
