This version includes only capital letters, and some commonly used punctuation.
My Dad goes hunting a lot. When he was growing up, one of his favorite tree stands at our hunting camp, Spring Bayou, was in the 3 Prong Tree. He killed many deer out of there. Now, the tree has fallen down, but the area around it will forever be called the 3 Prong Tree.
When I was writing some letters, I thought that using three straight lines to create each letter would look neat. So I tried it. On the letters without many curves, it turned out great, but the more curves required, the worse it got. That is why there are only Capital letters.
