Good stuff, Gilbey! Welcome ABoard!
Ya'kno, sometimes there's something in the "backyard" and sometimes there isn't.
Today for instance; dug for 2 hours didn't find anything, then walked a couple new sites for another 3 hours, (in the hot sun I might add), and didn't find anything but an old petrified plastic squirrels head and the broken basal portion of a projectile point.
You know how it goes.

Welcome to the lounge

You likely know about Nethers Farm on Flint Ridge and if not I posted an account in the Field Trips section of the Lounge.  I read up on prospects of central, southern and southwestern Ohio when I lived in Dayton (twice) or visited my in-laws in southern Ohio, but I followed up only on Flint Ridge.  If I had time, these are the mental notes I'd pursue:  Explore the road cuts in Adams County and look for signs of the probable impact crater near Serpent Mound and the oddball mineralization that occurred (Adams County has traces of more minerals than any other place in Ohio, iirc).  Explore the Paint Creek area of Ross County just to see the giant concretions in situ.  Look for fossil trilobites at Caesar Creek Lake.  Look in the creeks around Athens for petrified wood.  Look for septaria that supposedly tumble out of some of the cliff sides facing the Ohio River.  And just because the topography looks interesting, explore the "caves" area about halfway between Chillicothe and Jackson.
