I have had a few people ask for my mailing address, so I will post it here so if you need it, it is here. It is:
Nicolas Miller - Cuerpo de Paz
Apartado Postal 66
Antigua Guatemala, Sacatepequez
03001
Guatemala, Centro America
If you do decide to send me something, it is best to use the regular USPS and label the package with a marker as materiales religiosos. This supposedly decreases the odds of it being tampered with. The UPS and Fedex options are expensive and also can be taxed heavily on this end too.
