Sequioa NP :)

I'm planning on going to Sequoia soon. This will be my first time and it'll be a solo trip. I'm coming from LA and I wanna get there at sunrise. My concern is the food I'll be bringing. I'm not bringing a lot but I'm worried about bears getting into my car. I'm getting an airbnb so check in won't be until 4pm. I definitely don't want to buy food from restaurants either 😭
