It was pretty elaborate. He moved all the chairs into a line with a gap between them, then covered the chairs and table with every available blanket and towel.
Inside he had placed the kids table and chair, his sketch pad, pencils and pencil sharpener. He ran an extension cord into the tent so his pencil sharpener would work...
...and even included a lamp. He took all these pictures of the fort himself too.
When he emerged, this is the picture he had created. Two elk.
He took time out of taking photos to study a mayfly. His hand is there to compare size. This is one of the many reasons I love homeschooling.
