Am I crazy?

I can only hope that this huge undertaking will help decrease the travel bug that resides within me. If not, then I'm in big trouble. I don't know how many times I could go through this and I still have 4 months until we leave!! Christina happens to be one of the best travel buddies I could ask for and what's better is that we've been friends for over 10 years! The goal as of right now is to hit 4 different continents (possibly 5 if we snag a layover in Europe somewhere) over a 5 1/2 month period. It may sound quick to some but for us it's perfect. Our tentative/ideal itinerary is as follows: Peru, Argentina, Brazil, South Africa, Kenya, Thailand, Singapore, Malaysia, Australia, New Zealand and Tahiti.
Our goal: to experience as much of the culture of each individual state while finding a balance between what it is traditionally touristy and what is not.
I hope that the planning and actual trip documentation will provide not only some words of wisdom, usually discovered through baptism by fire, or just plain funny stories. I tend to have stories to tell about almost everything in my life, so there should be some comic relief along the way. Stay tuned and any comments or suggestions would be well received!
