Am starting to lean toward keeping them there safely until post-monsoon season, with medical support, supplies, and top level efforts to pump and shore up their "safety zone." Nothing better than a swift, daring and successful rescue but too many factors could turn this into a tragedy --- lack of time training the children, the excess silt caused by single file evacuations, panic, and, worst of all, rain. I'd want my child out yesterday but at this point might vote to keep him there, hopefully safe, until water levels drop. Don't know nature or results of risk benefit analyses.
What a horrifying position for the families, volunteers and organizers.
