Paul, Here in Ogallala, at Corey's West Wind, both nines start with par 3's. The first hole has OB on the right, and believe me, it is rather intimidating. The tenth has OB on both sides, is more exposed to the wind, and, is twice as intimidating. Both holes play at relatively the same yardage (175 from back tee)
My feelings are the later the archie can have the first par three the better. I'm getting sick of the predictable third hole par 3.
At Pacific Grove, which starts with back to back Par 3's, the locals get er done in about 6-7 minutes. While the touristas can take upwards of 20 minutes to play the opener at 150 yards.
