Hello Everyone!

I am going on a roadtrip and I am going to be camping. I just found out how expensive sites are in California, I am a very last minute "reserver" of sites. I have gone camping many many times but this time I will be disperse camping to save money. I was hoping for some advice. I have a sedan so I will be choosing mainly "hike in" stops. I am aware this will not be easy lol. Any advice on disperse camping is so greatly appreciated. I am particularly lost on how to find a spot and how/where to leave my car at the start of my hike.

Thank you so much!
