The problem with this is that the count is always greater than zero.   
The count($key) will always equal at least one.  The one being the  
orignating zipcode that you searched since even if you searched 1  
mile, you would still have one originating zipcode.  If there is a  
location at that originating zipcode it would also return a location  
query.  Hence my problem.
