They used to HATE us at the tournament. We'd hit a glow ball or 2 out there and then 2 of us would hit regular balls. We could tell the direction of the regular balls so if we found one of those we'd use it. We'd end up -5 for 9 holes. The we took it up a notch...
MacGyvered an old pull cart with a sling carrying a car battery. We would hook the car battery up to a 1,000,000 candle power spotlight. You could blind the guys ahead of us putting from the tee. We also had truck headlights wired onto the arms of the cart to turn on for putting. We were now shooting -8 for 9 holes.
We did it just to be pricks.
