Monarchs are also overwintering in Berkeley in Aquatic Park. First time ever! Or maybe: first time in recorded history! Those are easier to get to. Lots of people are going to view them since this article in Berkeleyside.

I wonder how long they will stay there. They could move on to another location. Or maybe the clump will get bigger and they will stay all winter. Time will tell.
