those painted lines remind me that on Old Rag Mt there are some occasional useful arrows for newcomers so they do not get lost going through the boulders.
There are several tight spots and at one of those an alternative wider route. A painted arrow said "fat people this way." This is now history. Could not find a picture of that non-PC marking, just general pics:
