> What kind of impact does dumping all that sand have? The sand gets wet and sits in the water. It's sand, i.e. dirt. In case you weren't aware, there's already dirt at the bottom of all lakes. > What about running the bulldozer over the Stanford campus? The ground would get slightly compacted and maybe some grass torn up. That's why they got clearance from the person responsible for that, the groundskeeper. > What if someone is injured by the bulldozer? They will learn an important lesson about bulldozer safety. > I wouldn't trust teenagers renting an after-party bulldozer who never cleared that with anyone, never notified anyone, and have no proof of training. If you ever find yourself running a bulldozer rental place, you're free to not rent to them.
