    You guys. My wife's uncle is a major model train buff. He built a 2000sqft train layout over decades and now he wants to retire from the hobby and just give the whole thing away for FREE. He asked me if I knew anyone...I want to help!

    Something special is happening in Barcelona. It started last month when some parents organized a bike ride to school for just five kids. Now entire neighborhoods are joining. They call it Bicibús – or Bike Bus.

    The city said it would take three years to install a speed bump. So I bought my own on the Internet for $98. 😊 Story here: substack.zachklein.com/p/the-city-sai…

    My 5yo asked, “How big is a wolf?” So I Google it... Google’s first result is the option (in browser!) to place a realistic wolf in the room with us so we can walk around it and see for ourselves. Magical. The closest I have felt to a Young Lady’s Illustrated Primer.

    This is a ready-to-go, major exhibit for any public space. Would be perfect for children's museum. Interested? DM me. I will only pass along very serious interest, so please tell me about your org/space/ability to cover shipping and install.

    My SFPD story: My house was robbed while we were sleeping. Guy cleaned out every thing valuable from the ground floor including family heirloom. Call cops, they show up 2 hours later. Give them clear picture of guy’s face and am able to track one Apple device in real time…
