I grew up in IC and graduated from the UI and now live in the QC
have you ever canoed the Upper Iowa RIver? it is about a 2 1/2 drive from IC, but worth the drive. there are some nice sections of the iowa River which are rather fun to paddle. The Maquoketa river is also a nice shallow river worth the short 1 hour drive. i have never paddled the cedar river, but it looks very similar to the Iowa River.
paddle on...
