“I’ve lost my vision slowly throughout my life,” he told CNN Sport, explaining that it wasn’t until his mid-20s that his condition – a neurodegenerative eye disease called retinitis pigmentosa – started to affect his dayto-day life, stopping him from driving and biking.“Eventually [I] got to the point where I didn’t think I could leave the house without a person, like a human guide or somebody, a friend.What can a blind person do?”The Michigan native started skating at seven, but got into it more seriously at 13, developing a love for the sport which he says helps him express himself.The park, set to be built in Mancina’s home state of Michigan, will use adaptive methods, such as increasing the size of obstacles, adding contrast to obstacles and using auditory cues to make it safe and accessible.“So there’s kind of more time to figure out where you are in the park, find your way around, easier to get on and off rails for wheelchairs and using a lot of contrast too, is important for those who have a little bit of residual vision between the ramps and the ground,” he explained."
