I love Keeney. I'm a Wethersfield/Hartford guy, and used to play Goodwin the most, but since they put the money into Keeney, it's quickly become one of my faves. I LOVE the grass range, and now I won't practice anywhere without a grass range.
I hit up Stanley in New Britain recently, and they have 27 holes, and great practice facilities-but no grass range. They DO have heated range bays for winter hitting though.
I played Rockledge and Keeney back to back last summer, and Rockledge may be longer, but Keeney had the tougher greens, and I shot higher there.
I play Keeney, Goodwin, Stanley, Rockledge, Portland, Gillette Ridge, Lyman Orchards, Minnechaug, and Shinnecossett the most. Gillette is the hardest, and Keeney may be second. I suggest everyone in CT hit up Shinnecossett on the shore. Holes 16-18 are amazing.
