Due to Mosquitoes we haven't been out there for few weeks now.. Most likely not going back until fall or spring. It a swampy woods. Mosquitoes just unreal out there. But all the Bottles we found from our favorite spot is 1890 to 1930's... The Fruit Jars only ones finding before 1890. I think it was very first dump site for Gary, Indiana... when they built US Steel and made the city. Because US steel was built in 6 yrs roughly and opened in 1906 and most of Gary 1906 to 1910... Then we have another spot further from lake.. which has more earlier 1800;s. But more broken stuff. Harder to sort thru. Seem the best condition bottle find there. Still has cracks or chips. Just not main great shape ones.. --- our 1890 to 1930 spot... Nobody been there forever... There no sign of people been there in over 50+ years... You don't find anything later then 1930's. They just in much better condition.. Don't even have to dig.. But we tried digging... all the same stuff just keep going deeper in the ground. But you can grab 100, 1910-1930 bottles just standing in 1 spot on the ground.... there so many... But being our spot so close off Lake Michigan... Somebody had to be transporting across the lake near there before that city made... Got to be an old port around there. Such there had to be houses before the city was made... There many old foundations scattered all around there. no way to even date they so old . and had to be torn down in 30's. ---- But I'd take $2 or $3 each just for selling wise.... I'd be rich. I can get thousand bottles a day from there and think I never make a dent in them... there so many. (the fruit jar got me collecting them.. was just everywhere.. Fill a tote in 5 minutes 1858 pat ones, no digging.. just everywhere) -- But they very well guarded with mosquitoes, swampy land and snakes and it a bit of hike thru it all... They'll still be there in fall & spring.. Then going to check around those foundations more.. next time.
