First your gonna need a lotta booze. The first trip is always stressful and learning to drink your nerves to sleep is a skill that will come in handy later on. Get a half gallon of cheap whiskey in a plastic bottle. Don't worry if it tastes like shit at first, you'll learn to love it. Once your good and drunk tell anybody you know what you really think about them and how they ain't worth shit. Once you burn every bridge in your hometown the road starts looking a lot nicer. Now get your ass to an on ramp or major state route. More likely than not you'll get picked up by some weirdo will tell you his or her theories on the wonders of the universe, mixed with side comments about being tweeker / junkie for the past ten years. This situation will eventually get ugly and result in rude advances and personal threats. Good thing you remembered to get drunk cause you'll swing first and think later and the next thing you know you're locked up on assault in some town / county you've only heard of in country songs. Don't panic, you'll probably be out in 30-90 days till then you'll start to think of being out on the street like visiting a luxury resort. Once out on parole, be sure to leave the state immediately. All dirty kids must have warrants. A warrant is like a sleeping bag, only housies don't have one.
Now go get another half gallon and repeat.
