Stewart L. photographed that portable neon sign at Don Armeni Boat Ramp last week. We couldn’t figure out what it was for, but tonight we caught up with its minders after Mike sent word it had shown up late today in the parking lot at 44th/Edmunds. They explained that it’s promotion for the Gates Foundation-led initiative PowerOf, encouraging volunteering and donating to help people affected by the COVID-19 crisis. The sign is scheduled to move on shortly; the online schedule says it will be in Columbia City the next three days.
