Volunteering in Ecuador can be hit or miss.  Everything in Ecuador can be hit or miss.  It´s how the place works.  Buses don´t show up, the power goes out or the government decides to change something and tell people about it the day before.  It keep things interesting.  Once you live here for a while you get used to it.  A friend of mine puts it this way, "You definitely learn to let go of expecting everything to work out and you have to adjust to that. At first it is hard, then you start to joke about it, then you learn to make do and find other ways to get things done."
