I was weeding the garden earlier and could hear Camron struggling with something for at least an hour. He finally asked me to come and look at what he had built and here it is. My thoughts were - I hate it. Already we haven't been able to water that area for two months and now the rest of the grass will die. Those wheels need to be stored in the shed. Does your Grandfather know you did this? But I stopped myself and instead said "That's interesting. How does it work?" I'll have to disassemble it tomorrow before he gets out.
