i have a question. when i start hitting clay should i stop digging deeper?
If it is hard packed clay, yes. As Tim said, an old dump site is just that, ...... a dump, usually where "it" was dumped over the bank or hill out of sight.
Herphandler, if you are truly interested in searching for, finding and recognizing "good junk" ........ I suggest you go to a bookstore and purchase a copy of "
Schroder's Antiques - Price Guide" and start by leafing through it from front to back just to familiarize yourself with all the different types of "collectibles".
And remember, one (1) "good find" whether it is in a
dump or at a
garage sale will be worth the price you paid for the book, ..... and which that will usually result in an infection called "
Antique Pox", which is incurable and makes one look in every nook n' cranny for another "good find". ha ha
