dear god (volcanoes that gave early earth it's atmosphere) please allow me to crush the souls of other riders I may encounter today, may I not cramp, nor hesitate at the sight of a large grade, grant me the fortitude to descend without fear and the providence to make it home alive.... and buy me a new bike you #$%^ ^&*#@$% #$%^&@# !@#%%$# or I'll kick you squaw in the nuts.
