You could probably use the Hacienda for a mailing address - i think
the project has used this in the past.
Hacienda Guachalá
Panamericana Highway Km 70
Cayambe, Ecuador
Sam might be able to give you a better address for the Hacienda.
However... mail in Ecuador is super super super slow. Post cards take
at least a month to get back to the states sometimes, if not longer.
Unless you are going to be there longer than the 6 weeks of the
project, I wouldn't really recommend having anyone send you snail mail
or packages. The mail pace may have improved recently and someone who
has stayed extra and gotten mail might be able to help you out with
this more. Hope that helps! Amber
