Wind
Two winds, one river, no mat
Genesee corridors shove a start sideways. Lake-effect from the other quarter is a different shove. February ice skids whatever you captured in October.
We ice a lane on purpose. We note which wind is running instead of pretending a calm Tuesday is the year. If your loop is inland and sheltered, say so — Ned will still run gust logic, but the ticket will weight ice more honestly.
