A little loose algebra and it's reasonable to assume that, in Portland, the segment of the population with SAD is at least 33%, probably higher. Correspondingly, the number of folks in the throes of full-blown SAD in Portland can be guesstimated at 8%. Only a small fraction of these people are diagnosed.

Customers gave us flatware. We purchased a pile of old plates and bowls for 10¢ each on Craigslist, I built tables. We bought a 3-burner camp stove on eBay for $38.
