I remember reading in the Sebonack article that the course had a bye hole which crossed the first hole, no? I also remember Ron Whitten writing that a crossover hole would ONLY work at a very private course that got little play. However, the only course I have played with this routing is the Dartmouth course, where not only do the holes cross, but they both cross a ravine, and you cannot see the players teeing off on the other hole. Funny, I thought it worked quite well, with 18 being a great finisher as a half par hole (470 yards) over and around the ravine.
Getting back to the topic at hand, does Lahinch not have a crossover hole, the Klondyke? This was originally designed by OTM, no? Therefore I would guess he is at least partially responsible for the phenomenon. But then again, isn't a crossver hole just designed to get the most out of the land that one can, so wouldn't the concept by its very nature evolve rather than be established by one architect???
