So, do you understand Constraints?

As I was running errands in the car Saturday morning, I was listening to NPR’s very funny automotive show, Car Talk. A regular feature of Car Talk is “The Puzzler”, a mental problem that seldom has anything to do with cars.

I mention this only because this week's puzzle is easily solved if you understand constraints. So, check it out and see if you agree!

And, if you catch the "inky darkness" reference, you and I will both know you are a fan of the show and the hosts, Click and Clack, the Tappet Brothers.
