Chip--
I'm a Long Island guy, and I'll vouch for Tallgrass. It's a fun course, with some really good holes, and when the wind is up, it can be a bear. That being said, I've also got some issues.
Considering it was built on an old sod farm, sometimes the undulations that run through both the fairways and greens seem ... well, let's get cliche and say they can seem contrived. In an attempt to create some blind shots, like that of a rolling seaside links, they moved a lot of land, and at times it's quite noticeable. As mentioned before, there is also a big man-made ridge and huge valley that creates an interior out of bounds. That whole area stinks, and although it comes into play on only a couple holes, it detracts from the overall feel of the course.
With that, there's also many good holes, and the overall feel is still one that makes for an enjoyable round. The tall fescues make it aesthetically pleasing and a couple short par-4s are terrific. I guess at times since it opened about 10 years ago, it was rated as one of the best in the area. It's a fun tract, but one of the best it's not.
