Interesting discussion, I might need to add these places on my GPS, because most of them are not the kind of place I'd consider stopping for much of anything. I know, I'm not adventurous enough
If I need food, or a bathroom, or gas I'm looking for places that are certain to have these things, not a small general store that might not even be open.
Here's one from my neck of the woods, haven't stopped there in some years, but I do recall they had some candy bars in their refrigerated cases, which is something I've been known to do (frozen/cold chocolate is tasty).
Westchester General Store (on OH258 west of Freeport)
