Whilst hacking around Oakmont yesterday I spotted something in the bunkers at the back of the 17th the green:
May not be so clear in this photo, but there are a number of dark spots in the two back bunkers on the side nearest the green.
Also, when looking at the above photo, what's the first thing that comes to mind? Well, besides being thirsty after that hill climb! It's a paw print. A very large paw print. A dinosaur's paw print???
As ever, take cares if wandering this course alone.
