I will have to try a knot theory and see if it helps my research.
On another note, I have begun to get really worried about the extreme drought we are having in Texas (but I am good at worrying and thinking of worst case scenarios). There is no real relief in site. We have begun mandatory water conservation. I also hope that my fellow Houstonians will actually try to conserve water in the home. I initially was worried about the foundation of our house, our oak trees etc. Now I am worried about running out of water, having to leave the state. This drought has me depressed to say the least.
