Going to the construction site to pick up rocks, just in time for the last good opportunity

What kind of experience is it to go to the construction site to pick up rocks? This time I came to the construction site to pick up rocks. Picking up rocks here is not as quiet as in the wild. There are noises from machines everywhere, no natural beauty, and the environment is dirty. But there are many people who come here to pick up stones, because it is easier to pick up things here, so I will try.
