We re-windowed with Andersen, price was competitive and they're working well, though only 4 years - so much better, unsurprisingly, than the 1975 originals (brand unknown.)
Low of 40 this morning - actually well before sunrise as we had a breeze by then. Yesterday's 60/31 brought the month average back to a bit BN, will be very close to my average after tomorrow, then a 3-4 day dive.
