You should come over to Saginaw. We launch at Zilwaukee. You can run the river out to the Bay and then up the Kawkawlin. (Stay on the west side of the mouth always)
You can then run south down to St Charles and Bridgeport. Can Easily put 100 miles on.
Lots of eats out there too! Castaways (Kawkawlin) Hooters (Baycity) Rustic Inn (st Charles)
Have fun!
