Shari ... never seen moss on a roof?  Wow. 

Wow.

Talk about locally exotic.  I never would have thought of this image for that challenge, but I guess it is!

We have moss EVERYWHERE!  On roofs, in lawns, even along the edges of shady driveways and roads.  If people here didn't clean and treat their roofs, ALL our roofs would look like this eventually!  I admit this is a very bad case, but it's really everywhere.  You know how they say moss grows on the North side of trees?  Out here, moss grows on the North side of EVERYTHING! 

Look at Denise's mailbox pic.

Moss!
