Yep and there were many reports of 100's to low 1000's
of monarchs clustering on the coast of Maine, Massachusetts
and Rhode Island last September.

Yes, some of the same late fall and winter cluster sites 
along the central California coast also function as early 
fall cluster sites.  Like there is a golf course site near San Francisco
that often has hundreds of monarchs in late September. Here
