Now I don't rightly know about Punxsutawney Phil and his legend.
It would seem to me, that if Punxsutawney Phil could not see his shadow, it would be because the sun was not shining i.e. the sky would be overcast, gray, dreary signaling winter is still here and will continue for another six weeks.
Conversely, it would appear to me if Punxsutawney Phil COULD see his shadow, it would be an indication the sun is SHINING producing a very spring-like day thereby signaling spring is quickly on it's WAY.
Why is it the other way around? If it's gray and dreary, he cannot see his shadow and THAT signals spring will arrive SOON? Come on.
At any rate, I have my own system. If my plants look like this:
Spring ain't even anywhere close to bein' here. Just sayin'.
