Last week I went hiking in the woods looking for prospective dump sites, and came across a surface dump back in the woods. There wasn’t a lot of hope for finding anything very old, as the bottles were mostly screw tops, dating to the 1930s. But, you never know. After about twenty minutes, out rolls an aqua insulator. The inside was full of dirt, which I had to pick out with a stick, before I realized what I was had actually dared to hope, which was that it was an early threadless one! Haven’t dug one in years, really made my day.
