Carson's workshop

Carson has decided that the area between the trees and fence in the backyard is his workshop. He will go back there and spend hours making various things with wood, tape, shovels, water...anything he can get his hands on. He recently made a potato cannon that is made of wood and pvc and shoots mulch. He also has taken his retro metal firetruck and is modifying it into a flying motorcar called Hychanilitis (I have no idea where he came up with that name). Last week, he took a 2x4 and painted it red and made a sign to let everyone know it is his shop. It says "Carson's Shop" if you can't see that.
