🚂💰 The first 8 holes at Stagecoach Greens mini-golf in San Francisco take you from the Gold Rush to the railroad era.
Each hole is well developed and themed around the origins of the city. Fun to play and look at.
Be sure to take tons of pictures! 📸

⛳️ Stagecoach Greens is a miniature golf course in Mission Bay San Francisco. Each hole has its own SF-related theme. 🌁
Nearby are plenty of food and drink stands (including Spark Social), so no need to start your round thirsty or hungry. 🤤

📚 Finished reading Timeless (Awaken Online #7) by Travis Bagwell. Time travel, massive battles and a new character (Cady) keep things moving post-Armageddon. A bit formulaic, but still a strong addition. Next book’s out in March - already pre-ordered!

🎡 Hilaire Hiler’s color wheel 🎨🌈
Step into a circular room at the SF Marine Museum and look up.
Hiler's Prismatarium fills the ceiling with a 30-color wheel from his self-developed chart, each color representing a different emotion or mood.

At SF Maritime Museum model Clipper ships show these fastest ships of their time. 🚤
Those Clipper Cards on display? They’re the namesake of today’s transit card, honoring the speed of those ships of yore. 🤯

Just finished All These Worlds (Bobiverse #3). The Bob count grows, Earth’s on the brink, and big AI decisions get made. Still not totally my SF style (super short chapters, lotsa plot) but a fun, fast read. Book 4 is longer… so will see if that changes.

📚 I recently read The Amazing Maurice and His Educated Rodents by Terry Pratchett. Rats gain sentience via magical waste. A cat joins them. Chaos and moral dilemmas ensue. 🐀🐈⬛🪈
This is Pratchet's first YA book in Discworld, and won the Carnegie Medal in 2001.

🌁🖼️ On the ground floor or the SF Maritime Museum, dioramas show how important the waterfront was to San Francisco’s development.
They visually and textually capture what life was like on the waterfront in the city’s early years.

That 55m indication for the drive home is new in Google Maps. Or at least: it's new to me. 😃📍
I love such simple, non-disruptive improvements.
Maps as a whole is not (always) getting better, but this is a change I can get behind. :-)

I wasn't somewhere tear gassed, but my car was parked in a spot that was eventually overrun by protesters when I went to get it yesterday.
Folks kindly got out of the way, made sure I could get to my car helped everyone chanting step back for a second. Then cheered when I honked and waved.

📖🛩️ I recently read Skunk Works by Ben Rich - a memoir full of surprising detail on the development of secret aircraft like the U-2, SR-71, and F-117. Great insight into how Skunk Works operated from the '40s to early '90s.

🌊 SF Aquatic Park & the waterfront 🏖️
At the western end of Fisherman’s Wharf, Aquatic Park connects the waterfront to a protected space meant for swimming, sailing, and relaxing.
It's a public place, right at the edge of the bay.

That unusual building at the head of Aquatic Park isn’t random.
Get far enough away and its ship-like shape becomes clear.
Even the stands﹠bleachers on either side blend in so well they feel like part of the ship itself.

🚂💨 There used to be a railroad going up and down Mt Tam.
The "Mount Tamalpais Scenic Railway" operated from 1896 until 1930. 🕰️
Gravity Trains could also take up to 30 people down the mountain at speeds of 10 to 12 miles per hour. 😱🎢🤯

I saw this SF based kids book in a local store. Since I prefer to read on my Kindle, I ordered it on Amazon.
Imagine my surprise when I opened it yesterday, and it showed a completely different book with the same title.
Clearly a mixup, but with no simple way to fix it 🤬💩

🏙️ We hiked the Verna Dunshee Loop on Mount Tam🚶♂️
It’s about 0.7 miles of well paved trail that takes you around the East Peak 🔄
On the southern part of the loop, you have gorgeous views over the Marin Headlands, Golden Gate Bridge, and San Francisco 🌉🤩
