Closing the park today (Thursday March 5th) while I recover from knee surgery for a bit. I feel miraculously good considering the procedure was yesterday afternoon.

Massive shout out to the awesome surgery center staff Palo Alto Surgery Center. What amazing, professional and kind people.

Special thanks to for the authentic John Hammond cane. Putting it to good use now.

Special, special thanks to my loving partner, who got me home, safe and sound and comfortable. (Also, Happy Birthday Jackie!!)

We are closed today for the Nation wide ANTI-ICE strike.

ICE OUT OF OUR COMMUNITIES

Cotton Crustacean will always be a safe space for all people that live their lives from a place of tolerance, equality, anti-exploitation, anti-racism, anti-sexism, anti-homophobia, and anti-fascism.

Please remember, some small and local businesses can’t close today. Support them and be empathetic. Times are tough and January is already brutal. Pay with cash. Don’t give a cent to the system today.

Our insanely soft Great Blue Heron zip-up hoodies were the not so surprising hit of Fall 2025. We only have a few left of the larger sizes (XL-3X) in the shop right now, but we’ve ordered more!

Go to Cottoncrustacean.com and pre-order now. You can select to have it shipped, or to pick up in shop once we receive them!

Don’t miss out. These sold so fast last year. Celebrate your love of Pacifica and local wildlife, and have the perfect light weight hoodie for these beautiful, warm winter days on the California Coast.
