@farmerman,
I miss the familiar orange roof of Howard Johnson's. To some reason there is no memory of what was eaten there, but, at one point as an adult I craved their macaroni and cheese and was thrilled it was sold in the frozen goods section of the grocery.
Other then that, and since I don't drive (again be
very grateful and relieved), I can't think of any other roadside eateries...
...unless you include the olive loaf sandwiches an aunt made for bus trips back to wherever, when leaving a visit in Saratoga Springs.
