My home course (Whispering Woods) shut down until further notice (the end of March at least). We've actually been getting out to play a fair amount for early March. The gates will be locked, too, and so nobody is even supposed to walk the course. It may not stop some, but it will stop me, as I'm not keen on breaking rules let alone laws.
I believe most every other course in the area is officially "closed" too, given Governor Wolf's mandate that non-essential businesses close, but that won't stop some from "taking a walk" on land where they pay membership dues.
I'm encouraged by some news about vaccines and treatment options, but I also think they're over-stated, and even if a vaccine became available today, it might still take many, many months to be widely available.
