I think these are just amazing. I think it is sad when they must be destroyed. I have always wonder if that artist is happy just because they created it and enjoyed or I wonder if they wish it could remain forever. I think it must be a little disappointing to have them washed away.
I am grateful for the pictures because where I live there are no sidewalks. We could never have that in my neck of the woods. These pictures are probably the only things I will see and that is fine. I would drive down the city if they had one announced publicly I think.
Anyway, I hope you enjoy these. I found the quite incredible and inspiring.
