Bob's never ending quest to escape

It snowed a lot here in SW PA recently - if you haven't heard. Some pics of the snow attached. It was too deep for the dogs to get through, especially because it was powdery at first - and sooooo deep (30+ inches). So Dan had to dig paths in the back yard. At first just a loop for them do their business and to get a little exercise. Then he went crazy and dug a maze all through the back and side yards. They had a blast (the dogs) and Bob could romp freely without his leash, as he couldn't escape the walls of the maze. But the snow got heavy and the crust stronger to the point that he could walk on it, and that was it!!! He began scouring the perimeter for some escape route. Here is a YouTube link to his escapades...

What a great movie! I just love love LOVE Bob! He is a very cool dog. At least you are having fun making pics and movies of the doggies and the snow. Can't wait to see the next installment of "Bob". :)
