Hola, que tal!
My name is Jahnavi and I left Austin, TX in mid-December with the intention of riding to Brazil.
I am traveling solo, but have not been as comfortable with it as I had hoped. I tried riding with another cyclist for a week, but the male-female dynamic (sharing hotel rooms, etc) wasn't working so well for me.
My intention is to find a female companion, or a couple/group.
I am in San Luis Potosi, and I've attached a map of my tentative route. There is a family arriving in Cancun mid-march who are headed to Panama from there, so if necessary I may make some adjustments so I can meet up with them in time.
Let me know if you're in the area and want to meet up!
