Is it possible to pick your location with Tor?

I know you can change your IP with tor but can you go as far as to say pick your city?

You can pick any IP address from Tor Network Map. So if somebody runs ExitNode in your city, then yes, you can pick up a city.

Thanks for the help but It is one thing to set the Nation but can you set the city?

No, you cannot specify city "in general" like you do this with country. Only by listing the exact addresses which you know are from that city.
