There’s plenty to be scared of at Pinehurst No. 2, if you’re a golfer. Those famed turtle-back greens. Those tightly-mowed collection areas. Those juiced-up native areas off the tee. Add it all up and even the best players in the world can struggle to break 80.

For the average golfers, it’s obviously even more difficult. And the USGA even came up with a tool to help weekend hackers figure out what they would shoot there. But it turns out, the scariest part of the property has nothing to do with how Pinehurst No. 2 has been set up for the U.S. Open.

Same here, Jessica. Same here.
