Since we'd stopped to party in a college town, it was likely around 2am, or so. We weren't exactly completely sober. 6 of us in a 1972 Buick, headed toward one of the passenger's parents' place. Northern Wisconsin. 2 lane "Country Road" through woods and farm fields. No other traffic for miles.
Someone needed a pee break, so we simply pulled over, and a few of us headed for the ditch. As they were beginning to get back in the car, along came another, and pulled over behinds us. Red and blue flashing lights, and a spot light, suddenly lit up the pitch black night. Luckily, no one was still watering the weeds.
The officer checked out the car, and all of us, with his flashlight. And, when the driver (surprisingly) was completely honest about why we'd stopped, the State Trooper simply smiled, and said, "Carry on! And, drive safely!"
He'd stopped to see if we needed help, and seemed to totally understand, and accept, the need for an impromptu "rest stop" by the side of the road.
We stayed where we were, for a few minutes, after he pulled out, and zoomed off. We didn't, necessarily, want to catch up with him, even as nice as he had been.
