1138. A web page about Portland tells us this about it:
Portland is on a lower latitude than Eugene, Oregon which is roughly 300 miles north of San Francisco
What version of Portland could they possibly be talking about here?
Answer to come. In the meantime, make your guesses in the comments. Good luck.
UPDATE: The esteemable Isaac Lacquedem solved the riddle; this one is, of course, Portland, Maine. Bonus points here for deducing it from the text; it was copied directly, with no edits, from one of the pages on the City of Portland (ME) website. It could have been Googled, but you obviously used your considerable smarts to arrive at the conculsion. Good on you.
