Yep, we have the same sign.
I got shown by my pro on an "intro to golf" course how to repair pitch marks, I was also told to repair mine plus at least one other if you can find it. I find pitch repairing strangely satisfying.
me too - it means I've actually hit a green from far enough out to leave an impression
Pitch marks become a real annoance during society and charity days. Non members at our course never seem to repair their marks/rake bunkers when on this sort of day. .
but it is definitely a problem with the older members at my place.
