Wausau, WI 1975-1976. We went out door - to - door witnessing at night, when it had to be 0 to 20 below. Well, of course, very few people opened their doors that night.
One did, ten minutes later, we were in a cop car, going to the police station.
Once the police figured out what we were about, they figured we were harmless, let us go, and actually gave us a ride back home.
The home in question was the police chief's house, and as his wife was the one who answered the door, I do not believe she was too happy with us.
