When Hearty Soles, Lacknothing and I were planning a trip to Devil's Lake, we noticed this IAT cache right along our route. Lacknothing had quizzed us in the car earlier, asking us which 2 rivers were connected by this canal. Having not done any research yet, I could only come up with one. Now I've seen the canal, read the signs, visited Wikipedia and a couple other websites on this subject. Very interesting. There are some old photos of the canal at www.wisconsinhistory.org/
On top of that, we're all attempting to complete the IAT - Half Trail Challenge and this cache gives us Columbia Co. So there were lots of smiles at GZ.
Lacknothing found it in the blink of an eye.
