Sitting here with my recently operated on leg propped up, watching the idiot box and a show was on that featured a Habitat for Humanity home build. After watching this show and having participated in 3 builds, I am convinced now more than ever that having the general public participate in these is a waste of time. When trades people show up, things get done...right the first time usually. One of my builds, my wife and i spent the day tearing off siding that some other team supposedly put up wrong and then it turned out the wall was crooked. Our work was a total waste of time. Another build, about 14 people walked around all day with paint brushes and rollers painting and repainting walls and trim because they did not have anything else for us to do. I don't need to do one of these to feel good about myself and thats all these seem to do for the unskilled volunteer groups. Your experiences?
