Nine-year-old Ben Pierce of Dallas was born four months early and weighed just 22 ounces.
"We were warned that he may be blind and deaf and have cerebral palsy among some of the other challenges," said his mother, Heidi.
The boy has overcome many challenges but is quickly losing his eyesight, and realizing his vision is worsening, the family decided to create a list of things to see before he is blind.
Alaska was high on the list, and on the trip here he has seen the Aurora and ridden on a dog sled with Iditarod racer Aliy Zirkle.
"It's really beautiful and pretty," Ben said of the Northern Lights. "It's like water colors going across the sky."
The family plans trips to Turner Falls, Oklahoma, to see Native American dancing, and to visit London and Paris next year.
