On November 9, 2021, Brolin penned a long, heartfelt message for his spouse, detailing their life together. The picture was complimentary of the things expressed in his writing.
In the photo, Boyd was sitting in front of Brolin as he drove a Harley Davidson. Boyd was elated as she smiled for the camera on her right.
The picture depicted the couple's love for a thrill.

"Ain't nothin' is nothin' without her," Brolin began the caption as he recalled the adventures they had had together over the years.
They had ridden through Joshua Tree National Park in California together and gone climbing "via ferratas" [sic] in Switzerland with American climber Dean Potter. Brolin and his spouse had also walked the trail to Everest Base Camp.
Brolin also mentioned they had visited Costa Rica just a month after being stabbed in that same country. He was incredibly lucky to have survived the injury.
"It miraculously didn't hit any vitals. The doctor said, on a lucky scale, I was about a 9.5 out of 10. If he'd stabbed me an inch below, I wouldn't have survived," Brolin told Men's Journal in April 2018.
Their wedding, too, was something of an adventure. They married in the blue ridge mountains with "scrappy California boys" as their look-outs.
He also recounted their arrest while driving bicycles along the Venice Boardwalk in "see-through iridescent onesies" on Halloween.
"Baby, we've done it all," he wrote. "And we're still goin at it, kids in tow."
He claimed, in poetic fashion, they were "as alive as ever," and he loved being alive with her because he felt his life to be great with his spouse's presence.
"Life is grand with you in it," he wrote at the end with heart emojis following the last line.
