"I like to yard sale or garage sale here locally and when I travel.  FYI. . . this type of sale usually occurs at a residential home or location.  I like to look at yard sales in Richland, Washington, because I've found some really nice things there.  This I believe is mostly due to the people who originally came to Richland.  Richland was built to support the Manhattan Project.  So many were Scientists with a lot of construction workers.  But the older folks seemed to take good care of their possessions. 

I was at one of the government specification homes and a woman and members of her family were having a sale.  It was early in the morning, say 0730.   Lots of neat older items from the 1940's through 1960's.  And there was the EC-1, sitting on the concrete surface of the driveway.  It caught my attention because of all the screw caps, knobs and such and because it seemed in really good condition.  I left it to look at other items, but before leaving I went back to it.  I asked the woman if it worked, and she said she plugged it in and the light came on.  So, I asked the next question. . . how much do you want for it?  And the answer would make you sick.  I couldn't pass it up.  But I really didn't know what to do with it, so it sat at my house for about a year before your purchase."
