A few additions:
Shennecossett in CT....Ross, with additions and renovation by Mungeam
Franklin Park in Boston....one of the first daily fee courses in the country. It was designed by Willie Campbell, the first pro, in the late 19th century, and was later remodeled by Ross. Bobby Jones used to practice here while attending Harvard. The course was resurrected in the early 80s as it lay closed and overgrown, and now has much improved conditions, a beautiful new clubhouse, and a thriving junior program on the edge of one of the rougher parts of the city.
George Wright by Ross...on the comeback trail, if polished it would rank among the best layouts in the city, public or private
President's in Quincy, MA...by George Wright and Wayne Stiles. A very short, quirky course with severe greens, and conditions better than ever.
Also Captains (36) and Dennis Highlands/Pines (36) on the Cape are owned by their respective towns, and offer resident memberships for something like $500/yr. They are very good courses, but towards upscale, as Cape prices mid-summer push green fees to $50+.
