 I have heard you talk about that before. It really does work. But I didn't know that it was clear. Yes, clear plastic. Six mil clear. Absolutely. I thought it was black. I thought that would be better. No, the black. What happens is we don't get the effect from the sunlight. We actually get underneath the black plastic, we get heating, but we don't get the effect of the sunlight, which multiplies it. So the clear plastic, six mil, too, it's got to be that thick stuff.
