what you all think was the cause of both the bird kill and the fish kill? are we talking about hours, days, weeks, months? >> for the birds it could be days. we should start hearing stuff back maybe this afternoon, tomorrow. we may send some to some different labs across the country. so we'll know something about the birds in a few days, i believe. >> all right. >> and it shouldn't be too long for the fish. we had some fish that were collected while they were dying, which is what you have to do to check diseases, and those are being taken today to a lab at one of our universities, the university of arkansas at pine bluff, where they do a lot of testing of that sort. and so it should be as soon as they can run the cultures we'll know if it was a disease or a virus or whatever. it shouldn't be too long. >> all right. then, david goad and mark oliver, thanks for joining us here on skype.
