The navigation channel is the area of waterway beyond the ends of the wing dams that you want to navigate (set your direction) through so you don't run into them.

There the navigation channels are the locks.

Locks are a hindrance to navigation... although better than a portage.

That's why the things being discussed are called navigation channels.

ETA: A navigation channel on land could be the path between two minefields. Troop movements to the other side would be channeled onto that path.

I got an email from the Wisconsin DNR saying that the Boat that we just bought has a lien against it. And the good news just keeps on coming. The dealer says that they will take care of it, but I don't trust them.

Oh boy...

Tell the person with the lein they have to buy a new prop. ;)

Don't lean on the boat.

That really shoulda been "Oh, buoy..."

Props, yo!

The Boat has a new Prop. I fixed it all by myself.

Heh...

Not that kind of prop, yo.

But no less a Mad Prop.

Good, and whatever else Captain K tells you to do. ;)
