So talk a little bit about what goes into that.

So I think every project has its own challenges.

Summerlin was one of those.

And I think that most people have seen as we've started developing this property, we've added some significant retaining walls and had to adjust and kind of pivot as we went.

But it's very important to make sure that you bring in the right people as far as the engineers go on the front end, know what your challenges are, but you also have to adapt as you go.

We were probably 50% done with this property whenever we realized that we were going to have to put a significant retaining wall on half of it.

And then we've had to do that throughout the project.

And so I don't know.
