Yeah Thailand is pretty awesome but I felt like 3 month stays would probably be best there. Traveling around on the roads was pretty insane and I don't know if I would have ever felt comfortable driving there. I'm sure i could feel ok in Mexico in certain parts but I would also feel like cartels were going to kidnap me potentially. I don't know.
I felt really good about the premise of living in Australia. But again it is way more expensive than these other places. I have heard a lot of people say Bali is bad ass but not quite as cheap as Thailand.
