NCerfromNY,
Now you have me checking the date on my Duke's Mayo....
When I was on the road for some years for long hours, and really couldn't stop in at a lunch spot, I ate more gummy factory-made sandwiches from C-Store coolers than I care to think about.
I just don't get sick. Maybe a cast iron liner?
Or maybe I've been very, very lucky, and cruising on borrowed time....
