I roomed with a guy I worked with when I first got out of the service. He spent 2 years in Guatemala, 69/70 I think, in the Peace Corp. He was no big humanitarian, He just didn't want to go to VietNam but wasn't the draft dodger run to canada variety. Being farm types around here, he lived in some remote village and taught them about irrigation, crop rotation, etc.
They taught him how to grow killer weed, he taught them how to make it more killer with a higher yield. they apparently liked each other a lot. He had a life size (6'3 around 270lb) wooden statue of himself they gave him when he was recalled home. Its pretty cool, having a cigar store indian of yourself.
I haven't seen him in 15 years. Last I heard he was living in upstate New York with some ex-model or something.
that doesn't help much i suppose but I thought I would toss it out anyway.
