since this morning. fema put out this figure, 90% of the structures have some form of damage: i talked to an official from key west who said that was too high an estimate. what do you think? >> reporter: well, you know, i don't know about 90%. it's so interesting because the structures that are along the atlantic ocean which took the brunt of the force are those on the inside that took the dirty edge, are fortified. some of the steepest damage is inside these keys where the houses aren't as structurally strong. i'll show you some video of marathon key. we went ashore. i saw this building that had -- looked like laundry hanging from the railings and thought boy, there's a sign of life and went there. it is so stunning to see what the waves did with all the sand.
