Thats what i was thinking. Is there any way to date these things?? This part of the city has been residential forever, and theres a 4lane hwy 30yrds from bayou and they run parallel its whole length, about 6 miles. The history behind my finds is what really intriuges me, its not their worth, or rarity, for the most part....just the story behind them. And i understand that most of the time with out extensive research it will most likely remain a mystery. Thanks for opinion!
