That would have been a killer i have heard some older folks say that they used them as skipping rocks in the river being flat they were great for that purpose
I sometimes wonder if Im not picking up someone elses throw backs by all of the brokes I find.
I got the same ol habitsIv found myslef thinking I found a cache only to realize it was one of my old piles ....I seem to load my pockets up while looking and than start picking the keepers on the wall back and leave the rest behind .... I use to bring home everything but wife doesn't like them on every window sill near the kitchen sink lol
