I remember when I just surfaced picked. The only difference is that I was picking at a surface dump that doesnt go deeper than six inches. Found alot of those karo bottles there too. My first dug bottle was a turn of the century cartmans ink. That was about a month and a half ago. Now I am finding BIM and turn of the century stuff and am having more fun. Good luck on future digs.
Thanx. I hope I do find more. Judging by the code O-I used on their bottles, the green perfume was manufactured in 1930. The Karo is way newer than most of the stuff there (People were still dumping stuf there long after it closed) it's from 1951.
