It's alot of walking to find what little I pick up. It varies from year to year but I check roughly 400 (+/-) cotton and peanut fields a week. I have maybe 5 that are really good fields to look in. Another 5-10 will give up a point occasionally and the rest are dead areas. I've got a pockets of fields that were ocean, beach or something a few million years ago. I find fossilized sea urchins, sand dollars, shells, coral, etc there. No arrowheads...just ocean stuff. Kind of cool.
Lee there are alot of CW sites around here but I just haven't really gotten into that. Never picked up anything form era but I have a couple of farmers that check a creek on their land and they are always finding mini balls and stuff. Had a friend clearing some land last year and they found 4 cannonballs. I just look in the fields I'm checking and point are the easiest thing to find. Find way too much broken stuff and flint chips by the millions. Just something to keep my mind occupied this time of the year when pest pressure is low..weeds hve been taken care of...but the heat is rough.
If it doesn't rain in the next few days and this heat let off a little it's gonna be bad around here.
