I am leading a group of Boy Scouts, looking for a canoe trip in Lower
Penninsula Michigan, Northern Ohio or even (close to Michigan)
Ontario.

Looking to do a lengthy trip, over 50 miles. Want it to be 4 or 5
days. Want to (to the extent possible) wilderness camp along the
river as we go.

We are supposed to travel only 3 hours from Metro Detroit (our
chartering organization puts us under that restriction, we can sneak
out to maybe 4 hours.)

Looking for as wilderness experience as possible, a little fast water
would be nice.
