Personally, I love the sixth hole more than the fifth, and maybe as much as the seventh, though not as much as the eighth!
I have not played it into the wind in a while, and most of the time nowadays I'm only playing from the middle tee. From the back tee, into the wind, it's an awesome hole. You have to hit a cracking drive to get up on top of the hole, and if you don't [which I usually can't], you are playing a 175-yard approach from the face of the fairway, blind up over the crest of the hill. I've hit that shot successfully a couple of times, and I can still feel the joy.
The green is a chameleon, and I think it's the biggest green on the course. Into the wind, you're just happy to get it on the dance floor and try to two-putt. The rest of the time, with a short iron in your hands, you are thinking about putting it in the right quadrant, and if you don't you'll be happy to get away with a four.
The trees on both sides of the hole pre-date the course. They are along an old road alignment, as are the two trees on #8, and possibly the tree on #5 as well ... the original nine-hole course stopped just short of that line, though I don't know if the road was moved further east down around #5 and #8 tee just before MacKenzie showed up, or sometime earlier. At any rate, it's an interesting tidbit to MacKenzie's routing of the front nine -- I don't know if they moved the road to accommodate his ideas, or whether he just arrived at the right time and was lucky that they got the property extended as it was.
