That's hard to say without knowing exactly how much it costs to sustain the PHM's collections or if they have other debts which would come into play. However, I see it more as a long-term possibility, if the NPS can be convinced to divert a bit more of its limited funds towards history. Sidenote-I was amazed when I heard how little of Valley Forge's park budget goes to the curatorial and interpretation departments when compared with how much goes to the natural resources department.
