That's a totally different bridge, Serena.

Then what other bridge has to have a stone thrown at it? The previous posts spoke of throwing a rock at a chain to lower a bridge........ which part is that if not there?

Upon further thought, I do realize what was meant and I was mistaken. A smaller drawbridge must be lowered by breaking the chain. My bad lol
