Echo location city in php?

I am adding content to GD Listing pages for each category and location. I’d like to dynamically add titles to the top of each listing page so that it says “Places in City”

I’m half way to my answer. I downloaded the PHP Code Widget plugin that lets you add code to a text widget. Then I added the following php which echos the category description.
<?php echo category_description( $category_id ); ?>

However, I’d also like to be able to add the location for each location-based category page. Is there php code that I can use to echo the category+location top description in the widget? I’d prefer to echo the city and state and not the country.
