For all the Spanish speakers here...

This is a non profit organization that guides groups of paying customers (profit goes to street children in guatemala)and groups of at risk youth through the mountains and jungles of Guatemala. The organization takes applicants with the following qualities to be volunteer guides:
-A 3 month minimum time commitment (not including a 10-day trial/training period beforehand);
-A minimum intermediate Spanish language ability;
-A first aid qualification;
-Some sort of outdoor or trekking experience;
-Good people-skills; and,
-The ability to work as a member of a team.
This would be an INCREDIBLE opportunity to explore the world, explore the wilds, hone your spanish and beef up a resume. One of my friends knows someone who volunteered and said that he only had amazing things to say about it. just do it.
