When Jane and I started doing Roadfood, I got kicked out of restaurants more than a few times because the owner caught me taking pictures. That meant that either I was planning to open a competing restaurant or I was some sort of muckraking reporter taking a picture of a cockroach I'd found. The idea of reporting on a cheeseburger or bbq or fried chicken was unheard of.
Speaking of Roadfood's early days, here is a picture I took inside the very first real Texas barbecue we came across, in the back room of a market in the town of Waelder, some time in the early 1970s. I like the cardboard-box decor! If you look closely you can see a knife chained to the table for cutting the sausage links -- a smokehouse custom we haven't seen in a long time.
