How many does it take to aim a dish?

Short answer is four. And it still didn't work. Rollie, whom we have known for a couple of years up this way, and is usually a dish man extrodinaire, just couldn't get a hit, even though he had a fancy sat finder. John, in the blue shirt, was nice enough to let us hook on to his permanent dish site on his site, so we're good to go for the next three weeks, nice gesture.
