Some sidewalk chalk art on the path at the base of Hippie Hill yesterday, alas mostly scuffed by the time I saw it.

Somebody solved the St Louis #Octothorpean #puzzle‽

www.octothorpean.org has many puzzles. Most can be solved on your couch; but some use details at some places. To solve one, you need to see a place in St Louis, USA. For years, that puzzle has lurked, unsolved. Until just over a day ago.

Current status: musing about crane operations on a day when it's too foggy to see the ground, relying on folks on the ground for feedback. I bet crane operators use this in similes for all kinds of situations.
two crane towers fade up into fog. A crane hook descends from the fog. You can hazily make out a crane counterweight at the top of the nearer tower.

I saw some sidewalk chalk art walking in #SanFrancisco yesterday morning.

At 20th and Irving, a skateboarding fire-demon-maybe by Kal Zakzouk.

At 4th and Irving, a mermaid by, I'm guessing, two collaborators.

#StreetArt
sidewalk chalk art. zooming in on top of skater. her hat appears to consist of a scarf, a cat(?) head, and a short sword through that cat head sidewalk chalk art. zooming in on top left of the skater. she wields a lollipop overlaid with a faint mouse skull. her arms are perhaps tattooed or are perhaps Frankenstein-ish combinations of things. sidewalk chalk art. a glowing crouching figure rides a skateboard. her shorts have a logo: '451F'. beside her hover eldritch symbols suggesting a transformation from ♡ to ⛧ sidewalk chalk art: an easily-recognizable fish tail connects to a human-ish figure seemingly drawn by someone still new to drawing

chalk marks on pavement: "↑ WET". More subtly, there is a clump of chalk dust nearby chalk marks on pavement. One set" "↖ W". The other: "↗ TE"

graph charting three numbers over the past two months. The purple line, test positivity%, was high a couple of months ago, but is now pretty low. The red line, new cases, was low a couple of months ago, and is now even lower, yay. The green line has jiggled and wiggled high and low over the last couple of months; lately, it's been high-ish

Some pics from walks in #SanFrancisco the past few days. lahosken.san-francisco.ca.us/new/2025/11/...
in the foreground, a retail street. behind, dimly-lit big buildings on a hill; when you peer more closely, you notice the one on the right is under construction. above the buildings hover some cranes, confirming that construction's going on. in the very background, colors of sunrise bright green leaves. at first you might think there's a bright blue strangely-shaped flower resting on the leaves, but when you look more closely, you see it's a soap bubble reflecting something bright (the sky?) patch of sidewalk with hints of color, where chalk has mostly washed away. Most legible is a partial signature @zakikal...something hemmed in by other buildings, we see a mural taking shape on the eastern exterior wall of the new building at Haight/Stanyan. The mural has clouds styled as in an old-timey Chinese painting, sunflowers, poppies, rainbows. Some purple geometrical designs with 8-way symmetry. It's pretty bright and colorful

Some chalk #StreetArt, I assume by Kal Zakzouk, at 20th and Irving in #SanFrancisco yesterday morning.
there's a lot going on here. inert human figure is somehow connected to various spiritual bits: arms performing mudras, demon head, antlers,… Uh, it's a lot closer view of the top-right part of the art

Some things I saw on my walk in #SanFrancisco this morning.

lahosken.san-francisco.ca.us/new/2025/11/...
wall with mural consisting of different-colored circles on a background of a geometrical regular wave. Below, some still-under-construction pavement and a traffic cone. To the side, a window with a little piece of paper; if this image were higher resolution, you'd see that the paper tells you that Jenifer Wofford and others made the mural fork in a path among redwood trees. the path is 'paved' with wood chips and needles. looking up, you can see the treetops, but they're kinda obscured by fog in the foreground, a sidewalk wiggles between a field and a grassy hill. drawn on the sidewalk in colored chalk are some circles and arcs which form a hexagonal construction suggesting triangles. in the background, trees obscured by thick fog. really thick fog. would you believe me if i told you there's a dog and a dog-walker back there?

I saw some art on my morning walk in #SanFrancisco today.

At the Animal Connection pet store at 35th Ave and Irving, a new-to-me doggo mural.

At 20th and Irving, some chalk art I suppose by Kal Zakzouk.

viewing this here bsky thingy via blacksky.community , which IIUC should be pretty similar to plain ol' bsky, but have some useful moderation built-in? Anyhow, let's see if posting works.

Walking in Golden Gate Park today, I was pleasantly surprised to stumble upon The San Francisco Old Car Picnic. I don't know much about cars, but I do appreciate a shiny paint job.

In the foreground, a bush covered with yellow-white webby stuff, something like dandelion puffs. in the background, the ocean and a big guano-spattered rock in the foreground, walking path by the bay with walkers and joggers. In the background, the Golden Gate Bridge in the foreground: a trail winds through rocky cliffs, dotted with shrubs. Beyond, a blue bay. Beyond that, the marin headlands, mostly brown but dotted with green tall sailing ship named Gloria
