I havnt. Maybe in S OK
As was said about selling in town, I remember in the mid early 50s, dad went to the market in St Joe Mo. It was a block square bldg with no walls, only roof. It was raised up off the street surrounding it by around 3ft. There were trolleys running around it, even tho they had replaced them uptown with busses. Some people sold out of there trucks, and some bought spaces and sold in the square. I imagine one had to pay something even if they sold out of there truck.
I also remember, after growing up and getting my 3rd job at a candy co in St joe that I walked up a street that had been the towns origional business district in the years between 1880 say and 1940. It also had dock areas, but the sidewalk was in some places built up, but that might have been as much to keep the Mo river out of the bldgs as helping to unload produce. Anyway, the stores had fresh ripe vegetables in them. in some places you could see vines, corn husks, leaves, ect trailing out the doorways. I have the idea now that grocery stores in and around St Joe came there to buy loads of fresh vegetables from the stores. There were railroad tracks either in front or in back of the stores, ive forgotten. The ones in front were more than likely trolley tracks. It was kind of a seedy, run down area. 2 and 3 story bldgs,. It was on 2ns st and around 2 blocks from the Mo River. There was another area like it. It ran for around 2 blocks N & S and only on one St. It had furniture stores, antique stores , a couple bars, and clothing stores,
