Yes, There was a woman riding her bike in the collinsvile CT area, when she was passed by a pace line, she got scared and tangled up with some of the pace line.
She sued everyone she could,the club, the riders she crashed with, riders that tried to help her after the crash and the shop that hosted the training ride.
I don't know of the out come of the lawsuits, I'll try to find out
"When the spirits are low, when the day appears dark, when work becomes monotonous, when hope hardly seems worth having, just mount a bicycle and go out for a spin down the road, without thought on anything but the ride you are taking." - Arthur Conan Doyle
