Description

Aside from the fact that my building has an ambient hum that has made sleeping (alternately) difficult or impossible for 26 months..... and aside from the usual noises around the Kilborn Allotment Gardens with trucks and bike path upkeep, and aside from the hospital helicopter a few times a day..... THIS unexplained HUM just appeared at about 7:10 am and as I upload this at 7:50, it is still going. No visible source. No explanation.
