How to change computer's location - wrong city

I know this is a question that someone is going to laugh at, but I am really stumped. How do you change your computers home location - meaning city and state? Whenever I do a google search for a business, the search automatically brings up locations in Tampa, Florida. Also when I search for directions, my computer always defaults to Tampa, Florida as my starting point. While I enjoy Tampa, I do not live there and would like to change this setting. I have looked all over system preferences and just can't find it. Thanks!
