After a wonderful layover in Oaxaca, we saddled up and cycled down the Pan-American Highway towards Guatemala. The road took us eastward through the heartland of mezcal production, then over a series of high mountain passes. After descending onto the Pacific coastal plain, we battled both the fierce winds that blow across the narrowest part of Mexico and a mysterious animal we found in our hotel room in the middle of the night. Our final stop was the bustling commercial hub of Arriaga, where we rested before tackling the big climb back into the Sierras.
