I've also lived in Florida for 5 years at several different times and I've
asked the same question. As to the portland-based signal I agree with
others' comments. I don't follow Cliff Mass myself but my son does and he
forwarded me this latest radar attribution. And as I recall Mass had a
similar attribution about a year ago which my son also forwarded to me and
also seemed incongruous. I think I saved that post on my computer so I'll
see if I can dig that one out.
