Oh dear,
last year I was on an organized ride during a thunderstorm. I was sure people would start looking for cover, but they all continued on as if nothing were happening. I asked a guy if we should maybe consider getting out of the storm and his reply was something to the effect that: he would be fine since his bike was full carbon--everybody else could do what they liked. I just kept going, figuring that there must not be any danger and besides, there were plenty of really tall people in the field that would likely get struck first, but in hind sight, that seems pretty daft. Luckily, no one was hurt, but I guess we could have been??
