Gary Meier was an early Volunteer serving in Ecuador 1962-64. Upon concluding our service four volunteers purchased a 20′ rowboat and floated down the Amazon River on their way home. Thirty years later Meier and his wife again arrived on Ecuadorian soil as missionaries with HCJB World Radio. During his twenty five or so years there, he penned a large number of short stories about his experiences. 47 of these short stories were recently consolidated into a book entitled An Ecuador Compendium – Stories from the Mission Field.
The book may be out of print but you can get in touch with Gary. The hyperlink has a description of the book and his email address.

Gary, I served in the Peace Corps in Ecuador 1964-66, and like you, I later served as a missionary in Latin America. I still support HCJB through Reach Beyond.
