No, dumb idea. Your parents will have called the police for a missing persons report and you'll be back home in no time. One of their children go missing in the night, yes, they will call the police. You're under 18, you will be back home.

I once had the bright idea to move to Vancouver when I was 18. No money, no ride, nothing. Long story short, I'd be dead if I did that. I would have lasted 2 days man.

Peace
