I took a little detour to stop by the iconic 710 Ashbury St house this morning.

A short clip from the last time I saw Bob Weir perform live at the Sphere in Vegas. Thanks for all the good times.

This is an "administrative warrant". It's not signed by a judge and is therefore unlawful. ICE agents carry stacks of these around in their cars and just fill them out on the fly.

Make sure everyone knows what this looks like, as they have already started going door-to-door in some neighborhoods.

I’ve been to Greenland. It is a beautiful place. It is insanity that this country’s president would contemplate illegally invading this land.

RIP Bob Weir. What an amazing life of music he provided. #GratefulDead

A few more photos from New Orleans. Short trip, but did a lot of walking in two days.

We are looking at some high King Tides events today and tomorrow according to the @nws.noaa.gov Bay Area office. If you are near the coast, stay safe and follow closure notices.

Happy New Year everyone! We are at the end of our 2025 earthquake year, if we follow the convention that earthquakes are recorded in UTC, and in Zulu time, it is 2026. I thought I would do a little 2025 California earthquake roundup for everyone (1/5)

I had a wonderful holiday with friends that I considered extended family in San Diego. I love SD and all of the scenery.

“Coalinga! There was significant earthquake in 1983”
Today’s drive from San Diego to San Francisco consisted of @timblor.bsky.social pointing out all the earthquake faults and geologic features to me and I pointed out all highway exits to state prisons, county jails, and ICE detention facilities. An interesting Venn diagram, I suppose…
