You want to call the STATE PARKS people, not the state forest people.
Both are part of DCNR. But they are different divisions within DCNR.
So, start with Lyman Run State Park, but in the winter time it might be hard to reach someone there.
So be willing to go higher up, and talk to the State Parks people in Harrisburg.
And if that doesn't work, contact your local state legislators.
If it is a vendor gouging people, that's not acceptable. The State Parks have a responsibility to manage the vendors to prevent such abuse.
