Blind skier Danelle Umstead is married to her guide skier, Rob Umstead. The two call themselves "Vision4Gold". Umstead is one of the few mothers competing in South Korea. Oksana Masters was born in 1989 in the Ukraine, near the Chernobyl site. Her disability was because of the radiation from the accident in 1986. When she was 7-years-old, she was adopted by a woman from the United States who said she should play sports. Masters tried very hard, and later went to the 2012 Summer Paralympics where she competed in adapted rowing. After the 2012 Games, she had pain in her back and changed to para-Nordic skiing.
