[python] Re: RWS

Here's another one - I was going home from work this tuesday with my
panniers packed with clothing and stuff for work. At the start of a long
downslope a 30km/h moped was gaining on me (normally they go about
35-40km/h on the straights). Behind the moped there was a Lance-dressed
hammerhead trying to keep up. When the moped was allmost at my rear wheel
I put the pedal to the metal and got up to 60km/h on the slope leaving the
hammerhead and the moped in my dust. I never saw them again. The average
speed on the 39km trip was 31.2 which I'm quite satisfied with :-)

Alas, I'm not ready for this on my Python, it was on my 'ol trusty 17kg's

Torben - getting ready for the Danish championship in June and World
Championship in August (anybody interested? :
