Why does my iMac think I live in a different state?

Sometimes, when I conduct Internet searches, the results I get for locations are in the state adjacent to my own. Most recently, I tried to go to the AAA website for my state, but the web browser keeps redirecting me to the AAA site for this other state. I have tried on both Firefox and Safari with the same results. Nothing I have tried will allow me to get to the AAA website for my state.

Is there something I need to do to reset my location?

I've had this Mac for several years, and it hasn't been a problem before.
