Making an Unnecessarily Fancy Ladder Ball Set (Without any Screws or Bolts)

My friend Jeff requested a custom ladder ball (otherwise known as Ladder Golf or Redneck Golf) set to replace his family's well-used plastic one. I set about with some red oak I had laying around to make a new set that was able to be set up and taken down without screws or bolts, unlike most of the DIY versions of this I've seen on YouTube. Let me know what you think of the design!
