The Wisconsin can't make it onto the Great Lakes and into Green Bay because the Welland Canal is too narrow and the ship's draft too deep.

The USS Iowa couldn't take it up the Mississippi to Davenport, let alone up the Des Moines River due to draft issues.

When People said the gasoline engine was not dependable, did that stop Henry Ford?
When people said no one would ever go faster than the speed of sound, did that stop Chuck Yeager?
When people said no one would ever break Hank Aaron's homerun record, did that stop Barry Bonds?
No to all. So to get the Wisconsin to Wisconsin and the Iowa to Iowa, all that is required is for bright industrious people to come up with ideas. And a couple of hundred billion dollars. Or maybe a couple of trillion. We need to stop thinking small here folks.
