This year nearly 30 states have experienced cuts to parks’ and sites’ budgets, and a recent survey estimates as many as 400 state parks could close.
The non-profit said the worst cuts were taking place in Arizona, California, Missouri, New Jersey, New York and Pennsylvania. For details, visit NTHP's siite here.
