I just read a good article about the actual number of bunkers. It says they can't really be counted, but that they number more than 1,000. According to the story:
. . . the eighth hole has the most bunkers (102), followed by the 18th (96). The 12th and 14th holes tie with the fewest (18).Read that again - 18 is the fewest number of bunkers on a single hole.
That's pretty amazing.
