An exodus of workers worried about pension changes is taking a toll on state parks.
Since late last year, almost one-fourth of the park superintendents have retired, taking with them in many cases 30 or more years of experience.
At least 23 park superintendents and another half-dozen assistant superintendents have left the state Department of Natural Resources since late last year. And department officials say they don't know when they will have the money to fill most of those vacancies.
