I really enjoyed your 'how to be culturally polite' section. Short directions that inserts into Interactive travel comments. You never know when you need help. Out of site, out of mind. Do not show people what you have.
People steal what they can see.
Walking around with a camera. Put it in a backpack. Always take a taxi, or bus, etc from bus station to hotel. Store you passport, travel check information in you email box. Put eyelet screw on if possible.
