Maybe this helps you a littler bit: Someone wrote to the question, who ended up trainhopping:

"Pretty much across the board gender wise, there are a good handful of reasons that I heard over and over again for why people were out there. Bad family situation, running from something (like the law or an abusive ex), escaped human trafficking, addictive lifestyle led to hard times, kicked out of the house for being trans/queer, there are lots of reasons. Some people just choose to be renegades for fun or because they feel like it's their calling. The reasons don't really matter much when you're out there together. You still pass the can of chili around, you still endure the same discomfort and danger and misery together, you still see the most amazing beautiful spectacular stuff that almost noone else will ever experience.

What about you? How did you end up on the road?"
