Make the payments on my GTI, buy lots of beer and weed and food, every once and a while buy a shirt or something.
Oh and pay off the credit card debt I racked up during the season.
But when I was 17 I worked full time construction for a month, made $1600 cash, fandangled a cheap flght to England, got a train pass for Europe, and spent the $1600 over six weeks travelling as cheaply as possible, sleeping with friends where I could, and basically just galavanting around all over western europe, getting drunk, smoking weed, and overall having a good time. I definatly highly recommend it, and its a lot more obtainable than you probably think. Just get a guide book and go.
