What's interesting and I know that happens in Florida, I'm sure it happens elsewhere, you have sometimes competing environmental interests, where if you are avoiding a wetland, and thereby moving the facility onto an upland, now you're invading into or gopher tortoise habitat, so you have competing environmental interests and you have to work through what's the best decision for the transportation facility, the community, the environmental considerations and how do you integrate all of these competing interests and coming up with a really good project.
