There are at least two ways to do this.
1. Just enter the city name in the search field and sort the search results-columns accordingly.
2. If the city is large enough, you can search by metro area.
Select Advanced Search
Scroll down to the section labeled, "Location"
Inside that section, look for the sub-section labeled, "Country/State or Metro Area"
Select "Metro Area"
Select the Metro Area that fits your needs. Obviously, not all large metro areas are listed. If they aren't, go back to Option 1.
Another option is to perform a partial zip code search. For example, instead of entering an entire 5-digit zip code, enter only the first two or three numbers, like "900" (Los Angeles) or "021" (Boston).
Can you tell me which city? I'll give it a try.
