I'll add a vote for slow play. We had a junior tournament yesterday with 55 high school players. We started with tee times at 12:40 PM and the last players BARELY finished before dark at 9 PM. One group took 3 hrs and 20 minutes...to play the front nine (and therefore the four groups after them also took that long, but they didn't have much choice). The course admittedly was set up tough and with long rough there was a decent amount of searching for golf balls, but good grief...3 hrs 20 mins!
