Thx. Now I get it. How come every time I ask a simple question, the answers come back, and I realize I am going to have to become knowledgeable in another "ology." I JUST WANTED A HOLE IN THE GROUND WITH WATER IN IT TO FISH IN! I did not know I was going to actually have to work at learning so much new stuff like: dam constructionology , construction equipmentolgy, soil compositionology, watershed calculationology, siphon systemsology, drainage systemsology, planktonology, minnowology, aquatic plantology, water colorology, water chemistryology, aerationology, marine biology, wildlife biology, invertebrateology for peet's sake, land reclamationology, forestry, timber harvestology, road buildingology, no more moneyology. When will I get time to go FISHING!?
