JQuery: How to AutoComplete "City, State"?
<p><strong>Question</strong>: How can you use the <a href="http://docs.jquery.com/Plugins/Autocomplete">JQuery Auto-Completion plugin</a> to suggest a location (<code>"City, State"</code>) for an input field?</p>

<p>Meaning, someone wants to type in <strong>"Chicago, IL"</strong> ... so they begin typing <code>"Chi"</code> and it auto-suggestions <code>"Chicago, IL</code>".</p>

<p><em>My biggest hurdles is finding a service that I can query to find out all US city+state names.</em></p>

<p>I essentially want to do what the StackOverflow "Tags" input form works but form "City, State" auto completion.</p>
