I spent the night struggling with the bricks under the gate and finally dislodged one. Digging was easy after that, and by dawn I was in the front yard. Not long after sunrise I hid in the garden and watched as the guards looked for me. They can't see me and think I'm still under the dog kennel. Ha! Then one of them carefully blocked my escape tunnel with a massive paving tile. They locked me out! They have now left the compound deserted, and I have the day of freedom to sample the soft grass and weeds in the front yard.
