Eep! -- Blogger in German from Heathrow

I am in the Heathrow Airport, and when I go to my Blogger page, it presents everything in German. Automatically. Isn't that special. I checked the Google FAQ and it says I need to set my default language to English in my browser. But it's already set to English.

I finally found this blog by Amit Agarwal that says I have to remove my temp folder and then set my default language at http://www.blogger.com/language.g. Sheesh! It would be nice if this were documented, rather than me having to search for a blog to do it.
