ty, like your sense of humor! i looked at your profile. noticed you are a biology major. that's what my degree was in; but i focused more on medical stuff, and actually didn't seem to learn too much of the "real" biology stuff like i learn on this website!!! If I wasn't in the medical field, i would love to be a pond/biologist guru!!! my hat is off to ya, study hard and good luck/study. one of my college roommates chose the biologist/wildlife route, and i'm so envious when he's out shocking fish and studying wildlife for the federal gov dept. of Missouri. that seems like a blast...but the grass is always greener on the other side...(if you fertilize and water and weed properly!!!!) mark
