These days, when I shop at flea markets, my main focus is the pursuit of my next article. I found a photo album of a family's trip through California, with the majority of images from the Golden Gate International Exposition that was held on man-made Treasure Island in 1939. According to a souvenir guide book that I also purchased at a local flea market, years ago, it was said to be the largest man-made island in the world, at one mile square.
