When I read the title I thought it was going to say:
"...is surrounded by hazards (aka penalty areas) on all sides?"
Love PD but had same criticism of Muirfield. If the gunch is impenetrable and balls are unfindable then it may as well be a lake, no?
I really loved the golf course, and it's probably in my top five all time, but I made the same point in the Mashie discussion. If you took an aerial view of the course and replaced all the native with water, it would get roundly criticized here. That said, it's not impossible to find your ball in the gunch. Ross Harmon found mine four times during our match, and it was at least advanceable every time, so it's not quite as bad as water. And probably more visually appealing. But it does require a player to decide to either slow play to a crawl, or just give up and take the penalty (tangentially, I never was quite sure what the local rule was there).
I'm not an agronomist, so I'm not sure what, if anything, could be done about it without adding a lot of extra maintenance. At my home club I'm pretty sure they mow the native down in the late winter/early spring, and it's pretty playable year round (though certainly easier at the beginning of the season. Not sure if there's something they could plant that would be both dominant and thinner. And I don't think you'd need to do it everywhere. For example, we've discussed #s 1 and 8 on this thread. I'd be in favor of keeping the inside of both holes fairly penal, while thinning the gunch to the left of 8, right of 1, and between 1 and 3. There's certainly no advantage to blowing the ball the wrong way on either hole such that a player deserves even more punishment.
