At the risk of being pedantic, the Mohonk TRUST was dissolved decades ago.
So that's why it was dissolved; I'd always wondered.
Anyway, out-of-touch oldies can be identified by their Mohonk Trust/Preserve nomenclature. One good reason for not yielding the Preserve to the state is that state parks may be subject to political whims to our detriment. True, a private preserve may also be subject to whims, but a smaller entity would be more amenable to its supporters, us et al.
