I spent about 7.5 months backpacking in Europe shortly after I dropped out of university ... wouldn't call any of the places I stayed as 'shady situations', though as always when you're travelling, things happen. I hit about 15 countries in that time, and worked a bit here and there, and even briefly, managed to fall in love.
I don't think it is a 'white thing' ... but definitely being wealthy might help. My grandmother willed be $5000 specifically for travel when she died, and I had about $1500 of my own cash to start with. Managed to not breach that dollar limit, but I did definitely rough it a lot. Carried a tent, and camped out in random spots, hitch-hiked, and took the cheapest train fares I could find most of the time. Even borrowed a bike from someone I hitched with and rode it around Luxembourg for a few days. Granted, I didn't hit too many of the ginormous cities ... mostly spent my time in more off-the-beaten-track. Cities I didn't hit: Paris, London, Barcelona, Amsterdam (well, for more than 2 hours on a train switch), Zurich, Oslo, Stockholm. Cities I did hit: Prague (brilliant, though I was mugged there), Berlin, Copenhagen, Vienna, Luxembourg, Antwerp, and a host of smaller places.
I think more than 'finding our roots' ... I didn't really even make it to Scotland/England where the most of my roots are ... people are looking for independence, and learning to rely on themselves and their own judgments. Also lets us see how other people live, and experience the freedom of just being for a while. No schedule, no patterns, just experiences.
I highly recommend it to anyone who'll listen ... I definitely came back a changed person, wiser and with a bit of a different view of how life back home actually is.
edit: I did almost no drinking, and didn't sleep around, so my money stretched a bit further than some.
double edit: this was before email was particularly popular, and so I wasn't there to blog, and neither would I now. I spent months out of contact with EVERYONE ... stressful to my parents, but essential to my journey.
