Stop in for a cup of coffee

5° above freezing here briefly this morning. Up the road a piece in one of the local Wino areas freezing and somewhat below most of the night. They have strange cold weather procedures in the grapes. They hate frost, when frost is probable they run the rain bird sprinklers, they don't have a problem with their grapes covered in icicles :realcrazy::wtf:
When water freezes it actually creates a little heat which prevents cell damage to the plants. Tree nurseries do it too. Not intuitive!
