The Marquez family hiked to the top of Yosemite’s Half Dome last month with their 8-year-old son, Peyton, who suffers from Duchenne muscular dystrophy (DMD).
"I saw the valley and it was all green and stuff," Peyton said.
There is no cure for DMD, which leads to muscle degeneration.
Ethan and Bonnie Marquez were devastated by Peyton's diagnosis last year, but decided their family still had a lot of living to do and they intended to do it all with their son.
The first experience on their list was climbing to the top of Half Dome.
Peyton's dad and some family friends took turns carrying the 55 pound boy in a specially designed backpack.
"I thought me and my dad were gonna fall backwards," Peyton said. "So, I just looked forward and leaned forward so we wouldn't fall off."
The group finally make it to the top where Peyton found a small patch of snow he used to make snow angels.
The family hopes their story will inspire others not to give up hope.
"This is a hard diagnosis to get ... but this is our story and we're living it," Bonnie Marquez said.
"Like any good story, there's gonna be laughter, there's gonna be tears, and your are going to fight for the hero and he is definitely our hero," she said.
