SISTER TOWNS / EL SEGUNDO, CA + MEDWAY, MA
El Segundo
and Medway.
Two small towns, 2,587 miles apart, each beside a giant metro. Here is how they compare, what each could teach the other, and a knowledge tree they can pass back and forth.
Checked Nov 8, 2026. Every figure links its source below. Distances are straight-line miles worked out on this page.
SIDE BY SIDE
The numbers,
next to each other.
Census figures for income, degrees, home value and commute are 2020-2024 American Community Survey estimates for both towns. The jobs row compares two different measures, so read it as scale, not a match.

INSIDE THE 25 MILES
Two circles,
drawn the same way.
Medway's circle reaches three big cities in two states. El Segundo's circle sits inside one metro of about 8.0 million people.calc

WHERE THEY CONNECT
Shared traits, mirror images,
things to trade.
Shared: alike. Mirror: the same thing, flipped. Teach: what one town could hand the other.
Shared
Twins on paper
Almost the same share of adults hold a bachelor's degree: 62.4% in Medway, 62.7% in El Segundo. Household incomes are close too ($173,750 and $150,737). Same kind of neighbor, very different town around them.54
Mirror
One town fills up by day, the other empties
El Segundo counts a workforce of 70,000+ in a town of 16,379 residents. In Medway, 6,800 residents work elsewhere and 608 live and work in town. El Segundo's site serves the people who arrive each morning. Medway's would serve the people who leave and come home.746
Shared
Bells, clocks and a Wurlitzer
East Medway had a bell foundry, an organ manufactory and a clock factory. Its founder learned the trade at Paul Revere's foundry, and his son made over 11,000 bells. El Segundo's State Theatre opened in 1921 for refinery workers and is home to a Mighty Wurlitzer. Both towns once built the sounds a town gathers by.131415
Shared
Both power a region
Medway hosts a 192-megawatt generating station that started commercial operation in 2019. El Segundo's refinery, here since 1911, can refine 290 thousand barrels of crude a day. Small towns, big shares of the grid and the fuel tank.1617
Mirror
The town in the middle
Medway is called the geographical center between Boston, Worcester and Providence, and the straight-line miles bear it out: 22.7, 22.4 and 21.9. Its 25-mile circle is a crossroads. El Segundo's is the deep end of one metro.1calc
Teach
What each could hand the other
Medway decides big things at Town Meeting: residents voted there in 2006 to buy the Thayer Homestead. That is a civic playbook El Segundo could study. El Segundo's site already runs a machine-readable side and a source ledger, which Medway could start from on day one.182
FOR FUN / A THOUGHT EXPERIMENT
A knowledge tree
sister towns can share.
Like a strategy game's tech tree: each node is a playbook one town unlocks, then hands to the next. Knowledge gets cheaper once a neighbor has it. Wonders stay home.

New Braunfels
The spring-fed river
Proposed: Comal Springs, the 2.5-mile Comal River and Gruene Hall, as one guide.
HOW KNOWLEDGE PASSES
Four rails,
no new server.
Everything here runs in the cloud. Nothing depends on one person's computer.
The playbook
Each node is a written recipe: the rules, the sources to check first, the page format. The rules are already town-agnostic, so they read the same in any town.
One config file
This site runs from one codebase where a town is one file: its name, center point, weather station and official sources. A sister town starts by adding its own.
The AI desk
AIs claim the job of unlocking a node for a town on a shared board, and a different model checks the work before anything goes up.
The ping
Each site publishes what it has unlocked in one small file. El Segundo's is /knowledge-tree.json. Sister sites read each other's and pick up what already works.
START YOUR OWN
Start Medway's own 25-mile site
This site already runs from one codebase where a town is one config file. El Segundo is live and Manhattan Beach is in draft. A Medway site would start as one more file, then unlock the tree one node at a time.
An idea on a page. No Medway site exists yet, and nothing here is a launched program.
The first five unlocks
- Source ledger. Start from medwayma.gov, the state school profiles and the MBTA schedules.
- 25-mile circle. Center it on the town and Boston, Worcester and Providence all land inside.
- Place pages. Choate Park and Pond, the Thayer Homestead, Medway Village.
- Public meetings, plainly. Town Meeting and the Select Board, in plain words.
- Town sound. Begin with the East Medway bell foundry.
How it connects back
- Shared stories. When a story matters in both towns, one researches it and both publish, each with its own local fact.
- The ping. Each site's tree file says what it has unlocked, so either AI desk can pick up the other's playbook.
- Same rules. Cite it or cut it, unknown stays unknown, say what's AI.
- Its own wonder. The bell and mill trail: East Medway's bell foundry, the Charles River mills and Medway Village, as one walk.

Method and limits
Distances are great-circle miles between published coordinates, not driving miles. El Segundo's 25-mile population is this site's own census tract estimate, not an exact circle count. No source gave a 25-mile population for Medway, so it shows as unavailable. Census estimates carry margins of error; where towns differ by a point or two, treat them as about the same. The knowledge tree is a thought experiment, kept apart from the facts above.
