... And I'd like to point out that one of those parks listed, the only one near me, happens to be in close proximity to a small airport.
Notice his use of the word drones. I made sure not to use that dirty word and he used it over and over.
And, he didn't cite any specific regulations.
Here's what PA law says:
http://www.dcnr.state.pa.us/cs/groups/public/documents/document/d_001192.pdf
There's nothing specific about model aircraft, but they can basically prohibit anything:
(i) Prohibited activities. Notwithstanding other provisions of this chapter, the
Department may prohibit certain uses or activities in a State park, portion of a
State park or State park facility.
The Department of Conservation and Natural Resources of the Commonwealth probably has it's own process for rulemaking, so they may have a specific prohibition on "drones" (or not).
