...does this bother anyone else from a routing standpoint?
Of course, for facility of everyday play, and extraordinary emergency needs of big championships (rain, etc) I wouldn't jump up and down too much.
But I still somehow don't like it, like the course (especially revered championship courses of the canon) needs to be played in the order it was designed to be encountered.
They've been doing this at the US Open since 2002, the PGA Tour since the 70s, and I question why they wouldn't begin Rounds 1 and 2 at 7 am...off of #1 and ONLY #1...they could still get 156 out in threesomes, with 10 minute(!) gaps and be done by 3:15 pm, plenty of light for a 5.5 hour round.
cheers
