So is this stuff growing all over the District now? Flickr user katatiu2002 captured this scene in Georgetown. That’s moss climbing up, what, 12 inches or so along that door? There is probably no lack of moss or mold anywhere in the city, given the amount of snow and rain the District has received. Maybe the insurance adjusters or mycologists among our readers could explain: Does this stuff grow especially well when saaaaay you never shovel the standing snow from your walk?
