Description
The origin of this project was me, as a casual farmers' market attendee, grossly misremembering the start date of early girl tomatoes. Ironically, I still haven't achieved that goal, because I couldn't find a suitable source with varietal level granularity online. I'm half dreading a "Why didn't you check X?" comment and discover there's some perfect local varietal data source, but that would really be the best case scenario.The poster is customizable per crop, and the pictures reposition heuristically. There's only two regions, SF and NY, with very different source data for each. See https://vertumnus.fyi/about/sources for methodology.A static poster is not the greatest form factor for a schedule with annual variation, and this whole project was a non serious side exercise. See https://vertumnus.fyi/about for more.The project was coded in a single 731 prompt Claude Opus 5 session over 22 days within a 46 day period, from July 20th to September 2nd, 2026. I've published the entire transcript, searchable and organized by chapter, at https://vertumnus.fyi/about/transcript. A write up, with the stuff that Claude was good at and its repeated code quality shortcomings, is at https://vertumnus.fyi/about/ai.

Discussion
15 comments analyzed.
Concerns raised: Carbon footprint of driving hours to farmers markets, Limited to only two geographic regions, Insufficient produce variety in data collection, Doesn't account for availability variation within market hours, Unclear visualization - y-axis unlabeled, second color unexplained
Feature requests: Expand to more regions beyond current two, Add data for specific produce types like avocados, Include early vs late hour market availability differences, Publish to Facebook with proper attribution, Extend to all regions/cities
