Join the ride through the desert, jump into the pickleball tournament (all skill levels welcome), and enjoy meals provided for the riders as we come together to mark sobriety, share stories, and support one another. Whether you’re riding, playing, volunteering, or simply showing up, you’re part of this. Come be part of something bigger than any single activity — come be part of the Ascent to Freedom. “We wanted this to be a fun day that everyone can enjoy. Come meet the Opicure Community and grow with us,” says OpiCure Foundation President Cullen Easter. In the heart of the Anza-Borrego Desert, this inaugural OpiCure event brings together people in recovery, their families, and the cycling community to celebrate sobriety, share stories of strength, and raise awareness about the opioid crisis. "By turning the simple act of riding into a collective ascent toward freedom, it shows that recovery is possible, community heals, and every pedal stroke can move us closer to a life beyond addiction," says Cullen. "The OpiCure Ascent to Freedom is about community, movement, and celebrating recovery in every form." OpiCure Foundation is a 501(c)(3) Non Profit Foundation focused on addressing opioid-related addiction and deaths. More information on the event is available at opicureride.com .

Photographs and Memories: Imperfect and Authentic

By Brice Weaver • November 8, 2026

By: Brice Weaver www.briceweaverphotography What happens when a photograph becomes your only memory of something you experienced? I recently came across an Instagram video of a woman looking through photographs with her husband, who had apparently suffered a brain injury affecting his memory. The photographs captured their first dance together. As they looked through them, she gently asked whether he remembered certain moments. I found myself thinking about that video long after watching it. For her, those photographs were connected to experiences she could still remember. For him, they offered a visual record of moments he could no longer recall. We take photographs assuming we’ll remember the moments surrounding them. But what happens when we don’t? What happens when a photograph becomes our only connection to an experience, a person, or a particular time in our lives? And what happens when that photograph has been altered so extensively that it no longer represents what actually occurred? We’re living in a time when artificial intelligence can generate convincing images of events that never happened. Digital editing allows us to remove people, replace backgrounds, alter expressions, and reconstruct scenes until they bear little resemblance to the original moment. Much of the debate surrounding AI-generated imagery focuses on creativity, copyright, and whether these images should even be considered photography. But I think there’s another question we aren’t discussing nearly enough. What happens when the photographs we create today become the memories someone depends on tomorrow? Now Imagine looking through your own photographs decades later, unable to distinguish which details were genuine and which had been added, removed, or generated. Human memory is already imperfect. We forget, reconstruct, and sometimes unintentionally change our recollections. Photographs have traditionally provided an external reference, even if that reference was never entirely objective. If we begin treating every photograph as something to be perfected rather than preserved, what happens to that relationship? That short video brought the issue into a much more human perspective for me. The couple wasn’t discussing photography, artificial intelligence, or photographic ethics. They were simply looking at pictures, trying to reconnect with moments from their lives. You don’t need photographs to show a better version of your life. You need them to show the life you actually lived. We spend so much time asking how to make photographs look better. Perhaps we should spend more time asking what we need them to remember. As AI and digital manipulation become increasingly sophisticated, where do you draw the line between improving a photograph and changing the history it represents?
