For those who have never done this, the rules are really simple but prescriptive. You are to approach Ripon and find another plane to follow, 1/2 mile in trail, at 1800 feet and 90 knots. Here is what the NOTAM does not say: NOT 78 knots, NOT 2000 feet, NOT 110 knots, and NOT direct from Ripon to Fisk.
The closer we got to the airport the lower the sun was on the horizon and the longer the shadows became. The haze was really getting thick and hanging close to the ground. It seemed the more we strained, the less we could see. We knew the airport was right out there somewhere.
