I think I need to ask, what is the deal with hunting old streets?? I have hit several(one was a major city street dating back to the 1840s), and have never found anything. Am I doing something wrong?? I have waited until they have dug out the maximum amount of dirt, and have gotten as deep as they're going and still....zip. I'm getting a little frustrated at it, I dont want to fruitlessly dig another street, especially after seeing some of the finds that have come from sites like that. Any advice is appreciated, thanx.
