Not quite as dangerous - but still potentially disatrous - I was riding along a "bike path" that was a road, but is now closed to motorized traffic, so we are talking fairly wide here so there isn't really much of a good reason to be over on the wrong side. Its really twisty and I was coming around a corner on the correct side. Right around the corner, coming towards me, but just out of sight, was a couple with a baby carriage! Nearly gave me a heart attack, but I know that its a hazard on this particular stretch so I wasn't going too fast. Yeah I'm afraid I did yell at them, but they scared me!
