Tom, did you ever give any thought to a par 5 at OM? Is the design concept thwarted if the typical approach (whether on a par 5 or a short par 4) is with a lofted iron?
Ed: Figuring out the length of the Road hole at Old Macdonald was really tough, because of the prevailing wind. If we kept it at 465 yards and played north, it would be out of reach for most visitors most of the summer; if it played downwind at the same length, they'd be hitting wedges in.
In the end, it fit better heading north, as the 11th hole. It will play as a par five for many golfers, but it's still a 4 on the card. We did build an alternate tee up at about 380 yards, which I think will be a long iron or hybrid approach for the typical visitor in the summer.
Macdonald, of course, became acquainted with the Road and the Stationmaster's Garden back in the 1870's. I'm sure the hole was not often reached in two shots back then.
