Im going to be gone for a long time. Thats for sure but I have to decide where i will begin. I could:
A) fly to Australia from USA (home) and then make my way to mainland Asia for Thailand, Nepal, India.

B) fly to Nicaragua and then make my way South to Bolivia as the final stop. I will be using public transportation or hitchhiking. This will be a lot of ground to cover.

C) fly straight to Columbia and then make my way through to Peru. Im looking forward to the beaches in Central America so this would be faster to Bolivia but miss out on Central American beaches.

I also want to note that Im looking into Indonesia travel to a couple islands including Bali. Any advice on this country in particular, let me know what you all thing!
TL-DR: Decide between South America or Asia as a basic travel itinerary.
