I played Oakmont for the first time last night on there and 5-putted the first 3 greens. Very lifelike!
Being more serious, the flyover and bird's-eye views are astounding. I've seen the photo tours that Ryan Farrow and George Pazin did of Oakmont back before the US Open in 2007, but I really had absolutely no clue as to the scale of the place or what the surroundings looked like. Gave me a whole new appreciation for the terrain and routing of the course.
