Yep, Cherry Pickers is what I have always referred to those machines as, pretty maneuverable. I find it hard to see how anyone can paint something so huge. They look so small up there, maybe not as small as ants, but still amazing how they can do such large painting.
that is what always intrigued me how they do such huge murals and manage ot maintain a sense of scale as they do
and good to know you also call them Cherry Pickers :)
