These are new. As the weather gets warmer probably a necessary precaution. I wish the teams of young men hanging them up had thought to take the advised distance into account, though. They were separated only by the thickness of the tree, one holding and one tying.

Thanks for your continuing information! There are so many discrepancies in these social distancing guidelines. But these are all so unprecedented, who knows how to follow the rules?
How are things in LA? Has the rain stopped yet?
