"How to leave" - plan a 3 day trip to visit ANYWHERE - relatives, a graduation, a tourists hot spot - then leave with NOTHING. One suitcase with clothing in it. Don't email plans ahead of time or talk about the trip. Round trip ticket so it looks like you're coming back. No money taken out of bank accountc. No 'goodbyes'. Then never come back. Cab drivers get rewards for turning people in - never share crap with them.
Great tips.
