Wagon

These children were going to use this wagon to transport chairs that were used for the elderly guests at the Sports Day. I have seen this kind of wagon in other places, too. I have seen city workers use this to carry tools, brooms, ladders and cut branches when they clean the park. I have also seen construction workers use them.

I took a close-up so that you could see the wheel. It looks like a bicycle wheel. See the frame around it? That looks like a good idea.
