During spring break we stopped at the picnic area at Washington on the Brazos State Park. While watching my kids and enjoying the spring day, I happened to look up and see this:

I asked the kids how it got there, Sadie came up with a story about elves. When T.S. heard "elf," he announced that an elephant put it there.
So, what's the story? How did that shoe get in the tree?
Again, possible blog giveaway--if more than four people comment, I'll pick a winner and send him/her a fabulous prize.
