In our side yard, we have a beautiful old orchard that is many decades old. Three pear trees, two apple trees, and a mulberry tree still bear fruit. This tree, though, is special. It's totally hollow, yet still throws these beautiful blossoms every spring, and delicious snow apples for fall picking.
When the triplets were 4, I took these pictures of them standing inside it's hollow trunk.
Now, 5 years later, I had them awkwardly climb back in to see how much they've grown.
