I've known Andrea and her family for years. Just recently, her brother Rusty and his family packed up and moved to Liberia. They're doing some great things over there.
She just posted about an orphanage over there that is in desperate need of a roof to keep the rain out. During the rainy season, they get at least an INCH A DAY for five months. These children are sleeping in damp (at best) beds.
Head on over to Andrea's Blog, The Train To Crazy, for a simple way you can make a huge difference for these children.
