I'm looking for some information that has been quite elusive. I'm a registered nurse, and would like to travel to a Third World country and volunteer with a medical missions group. Most of the organizations I've found offered 1 or 2 week stints. I'm thinking of going for 6 months, since my financial situation will allow it. I'd be more inclined to travel to a Spanish-speaking country, since I know some Spanish. Does anyone have any information about organizations that are involved in this kind of work? I'd appreciate any info--
