I know that the real-life venue for the next major is at Southern Hills as I just looked it up. Not sure why we are playing the next major @ South Hills Country Club other than it has a similar name

Not remotely like the real venue which is circa 7481 yards long (v 6415 yards for South Hills). This begs the question 'If the real venue has not been done for PG, why wasn't another US major course chosen instead?'. Plenty of candidates : Valhalla, Winged Foot, Hazeltine, Baltusrol, Riviera, Merion etc etc. I shall play whatever the admins decide

but wondered if this was an accidental oversight when the tour rotas were set up.
