Same here - bowls, pestles, beads. I found one spearhead many years ago... no arrowheads.
Sidenote: The original site of Fresno is on, and adjacent, to a field I have on the Kings River. We used to disk up lots of door knobs, glass bottles, all sorts of artifacts. And it's common to this day to scrap up old mule shoes from when they built all the levees back in the early 1900's.
