Itinerary

Flying by the seat of my pants, the details of my trip are yet to be determined! I'm going until the money runs out and hopefully that lasts 3 years. There are a few places I must be during certain times of the year. My itinerary is based around those rare requirements (i.e. Christmas in Switzerland and Trekking Nepal in November) and goes as follows:

LA--Puerto Vallarta-Buenos Aires, Argentina, overland Chile, Peru, Bolivia, Brazil-Gryon, Switzerland working at the Chalet Martin youth hostel for at least 6m, undecided Europe with parents--Nairobi, Kenya overland Tanzania, Malawi, Zambia, Zimbabwe, Botswana, Namibia, South Africa--India--Nepal--China--Bangkok, Thailand (fly to Philippines) overland Laos, Cambodia, Vietnam, Indonesia, Malaysia--Australia (working for several months)--New Zealand--South Pacific--Kailua, Hawaii, USA
