Have you heard of Camp Ronald McDonald for Good Times? It is run by the Ronald McDonald House Charities, and is basically a summer camp (there are some family/winter camps) for children who have or had cancer, and their siblings. It is the most eye opening, heart warming, and soul fulfilling experiences you could ever do!! You basically volunteer as a camp counselor for one week in the summer, the people are fantastic, it is completely free, and counts as approximately 210 hours or so of volunteer work. Look into it, it changed my life!!
