We only have data from the last two years that we've been doing work on, so we don't know, but we know we are now approaching temperatures in the 27.5 range. That's the kind of thing for which if we had more historical information we would be able to see how much more it has been. But we can hindcast, and that's one of the things we're trying to do now, from satellite images. By the end of this year we will be able to tell you more about that, but right now we don't actually have buoys in the water measuring continuously as we might have in Lake Erie, for instance, or Lake Michigan or anywhere else.
