Indonesia (Bali, Lombok, Flores, Sulawesi, Maluku, and many years ago, Java), Laos, Thailand, Cambodia, Vietnam, Burma, Tonga, Fiji and of course, NZ! I tend to head off on 6-week to 6-month stints.
... Back to Indonesia (Flores?) before heading out of SEA to Turkey, Greece, Hungary and maybe Morocco, Jordan, Portugal, Spain and Italy. It's an endless list really!
