Late Bus Notification System
Here in Minnetonka, the school district announces late buses by appending a new row to a Google Sheet. Helpful — but it means mornings are spent hitting refresh instead of getting kids out the door.
This is a Cloudflare Worker that runs every weekday between 6–8am, watching that sheet for new routes. When one appears, it emails any parent subscribed to that route, so they find out the moment the district posts it — no refreshing required.
