Volunteer in Ghana

This looks like an easy, relatively cheap way to explore Africa for a month. Any one wanna come with me? http://www.challengingheights.org/volunteer.html. Chris Im thinking a man hike would be an excellent idea... what about that trail from the Adirondacks to the keys? perhaps we could do an international trail, as an example xianyan province in china(epic mountins, pandas and bamboo forests). btw how public is this blog do we have to keep things x rated or can we talk openly?
