Well, then, on to the second holes. Both are par-3's.
Whitinsville's 2nd is a fairly short par-3, playing slightly downhill to a raised plateau green along the top of a small ridge. Miss the green by a couple of yards short or long, and you're playing from a bunker; mis-club by more than that, and you're pitching up over the bunker from further below. I agree with Anthony's take that it's one of the best holes on the course.
The case of the 2nd at The Dunes Club rests on its two teeing grounds, which are 90 degrees apart and provide very different angles of approach to the green, either of them skirting a large patch of open sand which stretches back toward the tee. It's been a while since I played this hole [on my last visit, I played #4 through #9 after arriving late], but I don't remember the green as being anything special, or making the most of the two different approach angles. [Also, one tee is quite close to #1 green, but the other is quite a long walk.]
For me, the green complex at Whitinsville trumps the alternate tee at The Dunes. Whitinsville +2
Note: I just noticed that Adam Messix has forwarded me his match play card; says he will check in to comment when he can. I will post his result with mine as we go. He had Whitinsville winning the first hole, but The Dunes evening the match on #2.
