I'm a relative newbie to the Fallout series, so forgive me on my new-ness to the series.
On the "overworld", for some reason, I cannot get to Klamath. I walk over to the city, and click the world/town button, but no response from Klamath or any other town (was trying to goto San Fran as per the walkthrough, but that didn't work)...What am I doing wrong?
Thanks!

If you are on the green circle, click the green triangle and you enter the map. ;) You could also click at the "town/world" button, if you have visited the town for at least one times.

Aha, I was about to ask this question too! Fallout newbie here...
