For people growing up in the northeastern U.S., ice-skating is a way of life, and Rachel Pickering was no different. “I think I started skating when I was about 10,” she says. “Everybody used to go skating. We had a little rink.” So she couldn’t resist when a friend invited her to go skating in 2009. “I hadn’t been skating for probably twenty years, but I put my skates on,” she says. ”I was doing pretty good, and then this little girl was coming right towards me, so this only thing I could do was just fall, and I fell on my knee.”
