The season of oysters is those months in the name of which there is the letter "r". That is what I know. You can order them by May.
My mom at the station said the same thing about the cold.
...Yes? should be. I don’t even know why ice cream can be a seasonal meal. Probably this is somehow related to the cattle hotel, with the ancient calendar.
This is an ancient belief, kmk, associated with the absence of refrigerators in the stations.
