When she was living in Denmark, my sister told me about going to see the Tour de Denmark go by.
She and her then hubby went out to the middle of nowhere in particular (in plentiful supply thereabouts, according to her), where they joined a dozen or so people hanging around at a crossroads. They stood around for maybe 25 minutes, till someone said 'Here they come!' And sure enough, here they came. Quickly. Then the first few went by: thwup, thwup, thwup. Then a second or two, then the rest all went by in a mob: thwup, thwup, thwupthwupthwupthwupthwupthwupthwupthwupthwupthwupthwupthwup thwupthwup, thwup, thwup...thwup. The excitement lasted 'ooh...several seconds.' Then the road was empty, the dozen or so people half-acknowledged each other, with a sort or 'well, that was....um.....' sort of shrug. Then everyone went home.
