Traveling alone is a big step in a person's life, because it's not an easy thing to do, to navigate a strange place on your own. Sadly, it's even harder for women, because they all too often find themselves the targets of the creeps of the world.
The only saving grace is the knowledge that even though you might think you're alone, that's not always the case. When you need help, sometimes a good stranger will step up to help.
Often, it's because they've been there before, too.
