Worth a trip from where? Knollwood is a fine club and fine course. Below Winged Foot, Quaker Ridge and Sleepy you've got a group of still well-maintained, historically interesting, courses in Westchester including Appawamis, Ardsley, Whipporwill, Wykagyl, Siwanoy, etc. Knollwood is clearly in that latter group. also fwiw, the courses in Westchester are generally in very good shape for this time of year.
