Dave, do you allow cheating? I mean, could I do the flip sometime this weekend, take the photo and save it to upload on the official date? The reason is that I have to walk to a park to find a rock and I won’t have time to do this on The Rock-Flipping Day. I do have bowls full of lots of small stones I’ve saved from trips to various beaches but the only thing underneath them is more small stones.
I love the project.
