>>1632537if you're going to visit multiple national parks buy an "america the beautiful" pass at the first one you go to. $70 will get you into all national parks, monuments, and rec areas for a year from the month of purchase.
>Is it allowed to sleep in car in CA btw?generally no, but reactions will vary depending on where you do it. parking lot of a walmart will probably be fine. residential street in malibu will get the cops called on you, but they'll probably tell you to move on without citing you as long as you aren't a dick to them. yosemite you will absolutely get a ticket for illegal camping.
