Milford/Cinci/Clermont co. fairgrounds - one of biggest ones locally.
No idea how many tables outside (75+), also a large interior set up.
Found tubes, parts, and accessories I was looking for.
However...seemed like one this year was about 2/3 of year before.
Good parking access, but it's a linear show so plan on walking to get to end.

Mound Park - fun, and much larger than last year.
Because it's a park, restrictions, well, no commercial vendors.
Got good deals on acft headsets, Hallicrafters S-38c, parts/pieces.
Parking in same lot as tables, so easy access.

Dayton (well, Xenia fairgrounds) Hamvention - The Big One.
Since the change of venue, then the Plague, I hadn't been to new location.
It appears we probably won't suffer likes of The Great Sewer explosion here.
Bazoodles of food trailers, a welcome change.
Don't bother parking at fairgrounds. Shuttle buses are free(!) and constant.
I had security concerns about remote lots, but they have volunteers on overwatch.
Comfortable shoes and bring water. I walked almost six miles and still missed a lot.
Expect crowds inside buildings. Infield and track completely full of tables.
Got a lot of great buys on obscure items, so it was worth trip.

Piketon hamfest - at the Pike county fairgrounds.
Inside room and tailgaters outside.
Not very big, but lots of interesting items, no commercial vendors.

Lexington hamfest (halfway between Lex. and G'twn) - fun trip.
Inside church community room, and tailgaters out back.

Portsmouth hamfest - had low expectations, and wasn't disappointed.
Lots of tables but only 6 - 8 occupied.
