Re: Volunteer Work in a Foreign Country
Definitely I think you should do it. You won't have another time in your life when you can do something like this.
Just make sure you completely understand the program, and talk to people who have already done it with that program.
Doing it without friends will be fine; you will meet people and can experience something for yourself.
Be prepared for some things you don't like about it, and think through in advance what you will do when you are unhappy, and what your commitment is.
I have a Peruvian friend, from Lima; not sure how much insight she could give you but I'd be willing to put you in touch. She is very, very enthusiastic about Peru (only unhappy with the government).
