Oh man, a few places.
On this particular trip I left Vancouver, Canada a little over a year ago. Mostly Thailand but about 9 other countries so far. Croatia was one of them (again), northern Romania was one of my favourite places to be for a month, Montenegro was nice and a small quiet island called Kalymnos in Greece was great to disappear and work. No distractions there, and VERY cheap. :) Like, HAHA cheap. 280eur small apartment for a month!
Next stop is Vietnam!
