So you decide to fix that drainage issue in the back yard and start digging. All of a sudden you are bringing up ash and glass. It turns out your yard and some of the neighbors is an old dump from the late 1890's. You heard they had value so you just can't throw them away and they are all over and in your way. Not much else to do but get them out. It's a small house and you don't have much room...so....we'll fill the drive way up.
You don't know much about them but you know they are old. Some are really interesting like "swamp root cures". There are lots of beer and whiskey looking bottles for a town governed by a major religion. Then some blob top things you've never seen before....could they be pop bottles?
Lots of colors and shapes. Winters is coming. I guess you will sort it all out in the spring.
But you didn't think about the winter and the snow and how it would fill the bottles and freeze. You lost quite a few that winter. You managed to find a collector to help you sort it out. There were a few that were pretty good hiding in there. But the percentage was small. Most of them were more common or "blanks".
