Maine. No neighboring houses could be seen from our place, and new salesmen were always amazed at the amount of business we did. Dad's motto was，"We sell everything."If he didn't have something in store，he would pick it up for customers on his weekly trip to Bangor.

　　One time Dad was in Bangor getting shoes for someone at a shoe factory. He saw big boxes full of shoes and asked about them. They were the mates(一双鞋中的一只) to faulty shoes that had been thrown away. He looked through the boxes and realized that there were usable brand­new shoes in there. He offered the manager five cents a shoe，Dad made the deal and got the manager to reserve any future boxes for him.

　　Of course Mom，his business partner，was more practical，and her first reaction was，"But what are you going to do with them？"Dad bought an old school bus. He cleaned it up，removed the seats and placed big containers down both sides of the aisle(通道)．When all was ready，the whole family helped to put the shoes in place. At first, it looked like we had plenty of room on the bus，but Dad kept bringing home more boxes.

　　There was no sign on the Shoe Bus. The only advertising Dad did was to place a piece of paper beside the store exit that read "Shoes $1a pair"．When folks asked about the deal，they learned it wasn't that easy because they had to find their own pairs. The attraction was a combination of getting a good deal on a quality pair of shoes and the thrill of the hunt.

　　To this day，I still run into people who talk about the fun they had searching for pairs in Dad's Shoe Bus.
