Places to sit and chill in my car?

I have to read A LOT over the next year as I finish my degree, but I have to have quiet to read. I'd like for that not to mean I'm limited to the library and my apartment though. With cooler weather coming it'll be possible for me to sit in my car with the windows down and read, if I know where to go. Are there free, safe places out there where you can just sit and read in your car, preferably with a decent view of the sky or nature? Bonus points if it's a place where I can occasionally see airplanes.
