A very difficult site to navigate. I did fine this:
https://www.dcnr.pa.gov/StateParks/StateParkPrices/Camping/Pages/default.aspxI guess it's standard price for all Pa State Parks. It has the fee at $15.25 and $20 for non residents for 2021. I was last there Sept 2020 and I remember it being $15 then. I don't remember seeing anything about non-residents, but there may have been. It is a honor system. There is a box with the registration forms/envelopes. Sometimes empty, and a strong metal box to drop the envelopes in. I usually don't pay till I leave, because I'm not sure how many nights I'll stay.
Having registered for the Dark Forest Star Party, you are all paid up for Fri. & Sat. If you come early, as you said you would, or stay latter, you will have to pay extra.
One is not suppose to use the electric for anything other than Astronomy. But everyone hooks their trailers up to it. No air conditioner though. I do use my Micowave and electric coffee maker. Know one has every said anything. The rangers are pretty lenient. I have heard Maxine Harrison of the CSSP Dark Skies Fund Asso. can be a stickler. I did meet some purist running everything off of batteries charges by solar panels.
No White Light is a big deal because of the visual observers. You will need a red cover over your laptop. I have had imagers complain to me that my red head light was too bright. You will need to fine a way to have all red lights inside your van. I run my imaging sessions from inside the trailer via Cat5 cable. Most run the session with a laptop next to their setup. Those Laptop Tents are great for that and a small table with a folding chair. Bring an extension cord 50 to 75 ft. and power strip. Ear plugs can be very helpful to get sleep. I have been next to all night talking observers and noisy early risers. Not to mention some real serious snorers. Those were the tent days.
If we get a clear night, you will see the Milky Way horizon to horizon. I have seen aurora once. It's not New Mexico, but not bad. It's just this NE weather.
