OK, so Molly and I are paddling this thing called the Mississippi River. It's long, it's big, and it's gorgeous. Especially the gorge (just look at the photo above from a trip Tim and I did last summer).  Let's keep it clean!  The Mississippi River Challenge benefits Friends of the Mississippi, a non-profit group that works hard to educate the public on ways to keep the river clean. They also organize cleanup efforts and restoration projects along the river.  So if you consider yourself a friend of the MIssissippi, please give!
