Walker digs, digs and then digs some more!

 Indoors, in the sheets and under my comforter. Outside, I don't even know what he digs for

 His favorite place to dig is on the beach though. We live on a lake and have a sandy beach front. He can entertain himself for hours digging in the sand for rocks. Then the rocks sink deeper and he keeps digging! It's a blast to watch!
