I just learned last night that Google has FINALLY fixed my bug report from back in December. From the post Google Thinks Queen Anne is in Las Vegas:
I accidentally entered my zip code of 98109 and clicked the Map link and what do I see? Las Vegas. All the surrounding zip codes work fine. I discovered a bug with Google.
It took three requests into the Borg to fix this problem, but it got fixed.
To all the people living in the 98109 zip code: You’re Welcome!
