It think it was in 2001, we had some substantial snow (about a foot), but the drifts were much higher. I have Pug dogs and they were actually able to "walk" over the 4 foot fence that surrounds our yard, into the front yard. They all thought they were being sneaky, but we headed them off at the pass. I acutally had to make lanes in the snow so they good go "Potty", and our back yard looked like a maze.
