Golfers familiar with Wisconsin's Erin Hills Golf Club say U.S.Open players who are unfamiliar with the course are in for a surprise.

The rough territory just off the course's fairways is rougher than professional golfers encounter on most private and public courses.

U.S.Open competitors will therefore have cause to be grateful for the club's extra-wide fairways.

Golfers got a first glimpse of the rough in a video shot by RBC Heritage winner Wesley Bryan during a recent practice round.Bryan shared the video, which reveals grass and weeds growing two and even three feet thick, just off the fairway.

This year Erin Hills becomes one of 51 courses, just six of them public, to host the U.S.Open.The course, located about 35 miles from Milwaukee, is located in Wisconsin's Kettle Moraine, a region of low hills and forests that support hiking, biking, fishing, and boating in addition to golf.

Caddies will have their work cut out for them, as the 2017 U.S.Open site generally forbids the use of golf carts except for handicapped golfers.

The club is postponing the start of 2017 public play until July 1.
