On the next "Sarah Palin's Alaska" episode, Sarah and Todd take their kids on a 4th of July tradition of fishing for salmon in Bristol Bay, the world's biggest wild salmon run. Todd usually catches the lion's share of the fish, but son Track makes his first appearance on the show, wanting to earn the title of captain on his dad's boat.
"My dad's one of the best fishermen around," says Track. "I got big shoes to fill."
The family also gets to see their cousin Matthew, a boy with Downs Syndrome who gives Sarah a lot of hope about her own son Trig.
"Sarah Palin's Alaska" airs Sunday nights on TLC.
