I came across a dump towards the end of last Summer. There were old cans and bottles right on top. I have done a bunch of research on the hobby and have to give it a try. Looks like hard work but some of the bottles I've seen pulled out are beautiful. Here are some links you may like if you have an interest. Feel free to discuss and share your gems here If you want to get out for a dig hit me up, I'm in.
