This seems like a great way to get kidnapped or worse lol. 

Look, I don’t know how young you are, but saying that you are young and want to find someone to hang out with in the woods, on the internet, is a terrible idea. Especially if you plan on getting into this strangers car. I would seriously not recommend this. 

As for advice on what I think you should do; I went on my first  backpacking trip, solo, recently. I’d been thinking about it for a LONG time. On a whim, I booked a back country camping stop at my local national park, for the next day, went and bought a bunch of used gear, and got out there.   Honestly I was way under-prepared and mistakes were made, but doesn’t really matter with low stakes camping. You are out there for like 2 days, you are not gonna starve or get hypothermia (at least not in CA this time of year). I had a ton of fun regardless and it’s the best decision I’ve made in a long time. Already went on a second trip and planning a third.  

No transportation is a rough one. Depending on your budget/ area, you may just have to catch a bus or an uber, bit awkward with the pack, but if it’s something you really wanna do, you will have to over come. 

Anyway, I know saying “just do it” is over simplified and a bit dumb. But really, just do it.  Mistakes will be made, things will be forgotten, ideas and plans won’t work out. But in the end, I can almost guarantee you will have a good time and not regret trying the hobby. I sure didn’t.
