Back in the 40's & 50's the whole area from and including States Landing to Blacks Landing was part of the old Castle property. The then owner subdivided the waterfront part of Castle Shore Road (trail) off, and made, States Landing Road (trail), Blacks Landing Road, and Birch Hill Road as ROWs for the new Castle Shore properties. Later on, in the 60's, the Bank of Wolfeboro together (rumored) to be the RI mafia got together and bought up the backland and created Suissevale. A whole other story unfolds here, but the bottom line is if your CSR property was part of the first subdivision, before Suissevale, then you are not part of the association. If your deed has the association in it, then you are most likely stuck. Thru its lifetime there were multiple bankruptcies of the association and examples of the same lot being sold to multiple people. Today, its strong and I think the legal problems have been worked out.
Its bad enough to have State rules (cspa) and taxes, and town rules and taxes, but to add an associations rules and fees on top, is a little much. Then again, you do get free water? (thats when it works

)
