I know that right now, where I live, if you hung anything white outside for more than about 5 minutes it would come back inside looking more greenish-yellow with all the pollen in the air.
That might damn well kill half my family by causing us to drown in snot.
Hanging clothes on a line outside to get them DRY?
What an odd practice. Where I live, that's usually a guaranteed way to get them thoroughly wet.
