Who knows anyone called Ridge!?

Bit too American for my taste.

@VCM At least there's one famous fictional Ridge. I'm more afraid about people not recognizing the German word as a name.

Anyhow, I find most grids here too British with references to cricket etc.

Too many possible groupings with all the geographical terms. You could make water-related, flat raised areas, ridges, etc. etc. I'm sure, if you're including non-English names, that some of the others could be found somewhere. And isn't Poland Spring just a brand of bottled water, not a soft drink?

@Ace Yes, this may be too hard. And maybe bottled beverage would've been a better category
