Quiet place to park and watch airplanes/stars/nature?

What are some good spots to park and just watch the sky/airplanes?

With all this craziness going on I’m looking for areas to just chill and listen to music in my car while watching the planes and/or the sky and nature. One of my favorite, and only, spots to do this is at the official airplane viewing area. Looking for other quiet places that are legal to park in as I don’t want to trespass anywhere, surrounded by mostly nature, and that I’m able to go to 24/7. I know Houston doesn’t really have any scenic places, as long as there’s trees and minimal people I’m cool with it. Can be an hour or two away from the city, gravel or grass it doesn’t matter, if I can park and not get stuck it’s perfect.

Would prefer if it’s in the northern area of Houston, thanks!
