I can help answer your questions, I’ve been to Song School many times. After a layoff of a few years, I’m coming again this year.
For your first question, a PB staffer can answer accurately. I think it was limited to 150 people in the past, but might have been bumped up to 175 a few years ago? At any rate, it’s somewhere in that ballpark. It’s a small group of people in a large, beautiful setting. You will have no problem going off and finding some solitude to work on a song, or just sit and contemplate.
Vehicle: again, a PB staffer can correct me if I’m wrong, but in the past, you can have your vehicle at your campsite IF you camp at the main campground. If you camp backstage (a smaller area), vehicles are not allowed. You park at the gate, unload, then move your car. Are you staying for the Folks Festival? If so, then you’ll need to buy a parking pass for your vehicle if you’re camped in the main campground. Vehicles are not allowed in the backstage campground.
Now for the last question-- stuff to pack: the most important thing is to bring beer and wine for the Song School veterans who answer your questions. Just kidding. Sorta. But seriously… the basics are a tent, sleeping bag, clothes, instrument, notebook and pens, and something to record song ideas on (handheld recorder is my preference, laptop or cellphone works too). And…
You should assume it will rain at least one day. So be prepared.
Regarding clothing, I used to tell people that it gets cold at night, so bring a hoodie or fleece jacket, wool cap, etc. But global warming has escalated the last couple of years, so that’s almost obsolete advice now. Now all you need is a flannel shirt and jeans at night. Check the National Weather Service forecast website on the day you pack: http://forecast.weather.gov/MapClick.php?lat=40.2247&lon=-105.2714
btw, I mention night clothing because at night folks gather in song circles and pass their songs around. A lot of magic happens at night. You won’t get enough sleep, buy you’ll get memories that you will never forget. And a light hangover from the bottle of whiskey that was passed around with the songs…
If you’re coming from out of state, don’t worry about bringing food and drink. You can walk 1/4 mile into town and buy food at the local grocery, or eat at one of the restaurants. And there are liquor stores where you can buy beer and wine for the people who answer your questions.
Looking forward to meeting you in a few days!
