When you arrive at the nature center, turn your iPhone screen red to preserve night vision! This is helpful to allow your eyes to accommodate to the dark, reduces glare, and is less disruptive to wildlife. I didn’t even know this was possible to do with the iPhone, but this is an amazing trick for astrophotography.
How to turn your iPhone screen red, improve sleep and health by blocking blue light

Chaos and Catharsis:
Meaning, Music and Movement for Uncertain Times
Meaning, Music and Movement for Uncertain Times
Chaos & Catharsis is a speaker-led series for a moment defined by overlapping crises: climate disruption, economic instability, democratic stress, technological risk, inequality and polarization, information manipulation, and widening loneliness. Each gathering features a talk and facilitated discussion that explains what is happening and focuses on what we can do next, personally and together. Brief participatory moments help neighbors meet and connect. Simple breath guidance helps us to reset the body. We close by inviting the room to sing together in accessible ways that build unity. The intent is to leave with clearer thinking, a steadier nervous system, and a stronger sense of community. Learn more at ChaosAndCatharsis.com
