I think that solo travel can be one of the most rewarding experiences of a person's life. You do, however, need to come out of your shell a bit and be willing to talk to strangers. When I was wandering the planet I met lots of people that I remain friends with to this day just because I said hello at a bar. I think that most people are very receptive to talking to strangers and if they aren't, well, you didn't really lose anything by trying.

Solo travel is the best and people should not be afraid, especially now that we have all this technology to help make it easier.
