I was fortunate enough to travel to South America for 9 months from October 2017-July 2018. The trip spanned a route from Panama (not quite South America) all the way down to Ushaia, Argentina. I wrote two, lengthy posts during my trip recapping it.
The first one can be found here and was written in January 2018.
The second one can be found here and was written in May 2018.
In 2015, I was fortunate enough to travel to Southeast Asia from September 2015-December 2015. This trip completed a loop from Thailand, Laos, Vietnam, and Cambodia.
I wrote an email update in November 2015 that can be read here.
