that's where we have dave mattingly. he has been keeping an eye on things there for us. you had to take a boat tour to get an idea of what's going on there, dave? >> it's hard to back up far enough to get a perspective on how much damage is being done. this is so slow moving. and it's almost like there's a big lake around us and not a flooding river. but we did go out in a boat. we looked at some areas, industrial areas with equipment in the water, raw materials in the water, a sewage treatment plant with equipment in the water. the water is just inching up. the concern is for a couple of thousands of pieces of property in the memphis area. officials pinpointed those to figure out the water will come up about two more feet. so we know exactly who will be hit by this. so they're going around right now as i'm speaking to these houses, they're putting these fliers on them. these are clear. the message behind them, evacuate. your property is in danger right now. don't wait. evacuate. that's what they're trying to tell the people, to make sure they know don't be complacent whe
