I have hit the cart path on the right on #4 during my last two rounds, and in both cases, the ball kicked into the fairway. Must be the friendly squirrels (more on squirrels below).
So can I pick my ball up in the fairway to see if it's damaged? Per Rule 4.2c:
If you reasonably believe that your ball has been cut or cracked while playing a hole, you may lift it to check.
This is one of the instances where you can't clean your ball when you pick it up. You must recreate the lie that you originally had.
The squirrels at Balboa are so friendly and domesticated, that a kid was feeding and petting a squirrel while waiting for the green to clear on #8. I think that's a little too friendly.
