speedbumps on the highway to fluency

I am introducing a new and regular (ha!) column today... well probably just the idea of it right now since class starts in 10 minutes. It's called Speedbumps on the Highway to Fluency, and it looks at intricacies of the German language that, no matter how close I come to fluency, still trip me up regularly. The idea is, if I take the time to write about it and wonder why I keep getting it wrong, I'll figure it out and stop sucking.

The column is dedicated to the German word for speed bump: Geschwindigkeitsreduzierungshöcker.
