Here are the boys on another bridge, this time over an outlet steam that gets its source from the Greater Falls. The rush of the water fascinated them. I've got a picture of it further on. Susan is blessed with an acute sense of vertigo when over running water, so she refused to even step up to the railing. Come to think of it, she pretty much stayed out of my camera's way the entire week. Except to complain "Are you taking that thing out *again*??"
