South America travel buddy?

Hi,
My name is Shad, I'm a 37 year old RN. I am flying into Lima Peru Aug 29th and plan to see as much of SA as I can. I want to volunteer along the way. I have been using workaway.info to plan where to stay, but am very flexible. I enjoy traveling alone, but its always more fun with a friend. I don't care if you are male or female, as long as you are honest and not into finding trouble. I am easy to get along with, have traveled before out of country and am developing my espanol. Haven't decided to use a bicycle or buses yet for travel, I guess those are details we could figure out. If this sounds good, drop a line. Thanks!

PS. After SA, I plan on moving on to see Africa......or whatever turns up!
