summary: Product idea notes: A whiteboard with a rain cover that attaches to the lid of any cooler. To keep track of what is in the cooler without opening it. A few sizes for different popular coolers. Marker snaps and is attached in with a lanyard. Maybe a clipboard with a pencil would be easier as long as it had a rain cover. tags: - ticktick project: "\U0001F4D4journal" priority: P2 delegatedto: "" subtasks: [] dependencies: [] created: 2026-04-06T19:15:18.769997-04:00 resolved: 0001-01-01T00:00:00Z due: 0001-01-01T00:00:00Z
