Seems to be focused on Chicago (yay!), but there's lots of interesting data to analyze for prizes. Might be fun for the "data scientists", etc out there. Disclaimer: I have no affiliation with Divvy. In fact, I find their riders in Chicago pretty annoying.
There's lots of location data to chew on, especially relevant to geospatial folks.
