The Mississippi is dying, and I want to record it.
I just graduated from college, I don't have a job (by choice). I want to do something awesome. I want to ride a boat from the start of the Mississippi (Lake Itasca) down to Lock and Dam #1 (the first large amount of human control exerted over the river, and conveniently located near my house). I want to take water samples the whole way down (hopefully with some kind of real time chemical sensing equipment). I want to collect this data, put it online (raw data), and build a visualizer for it overlaying Google maps or something. I'll put the raw data up so you can do something cooler with it.
I would like this project to spark interest in other people to take care of their water sources, I want other people around the world to take on similar projects. I want people to realize that the environment is not an unmovable object, but humans may be an unstoppable force until we go too far.
