A month or so ago I was given permission to walk a local course in FL that is typically "cart only". The course has Bermuda fairways and the proper way to fix a divot hole is to fill it with sand. Early in the round I realized that without a bucket of sand, I was going to leave the course in worse shape than I found it, I retrieved my divots but I know the Bermuda grass doesn't grow back when a divot is replaced.
What do courses do in the south when walking is permitted? Does every player carry a jug of sand or does someone sand the divot holes at the end/start of the day? When one has a cart, the sand jugs are typically attached near the door frame. I do not recall ever seeing anyone walking and carrying a jug or bucket of sand.
