Anna and I are going to check out an urban section of the Rock River via Bike and Kayak. Will go something like this.

Leave car(1) with bikes at take out of Blackhawk State Park.
Drive car(2) with boat up to Green Valley Sports Complex in Moline.
Paddle down river about 6.5 miles
Lock up Boat at Blackhawk State Park
Ride bikes back to starting point about 8 miles.
Pick up boat and go home.

If anyone is interested in doing this (or something like this) with us let us know.
