A couple middle-school kids I know want to go on an academic (science) school trip to a Central American country. They don't have the money and their parents are strapped. Would attempting to crowd-fund be a bad/dangerous thing? Is that a universe kids should not enter? Asked for fund-raising suggestions, I thought it might be good, at least as a way for family to donate online. But I don't want to set them up to be identified, targeted or mocked by the world. Thoughts? Good, bad?
