Whenever we kids visited my Grandparents on their farm in WV, we always looked forward to the food ruck on Saturday mornings. It wasn't like a modern food truck. It was basically a grocery store on wheels. The guys running it would bring a bag of feed if you ordered it the previous Saturday, sold kerosene for folks to use lighting their stoves, etc., and had 3 cent chocolate candy bars when they were 5 cents everywhere else. They also bought people's farm fresh eggs, which, while fresh off the farm, had most likely sat on the floor of the pantry until they were taken to the truck. The truck eventually stopped running as costs increased and most people had access to a motor vehicle of some kind, but while they operated, they provided a valuable service to many folks who either lacked the means to get into town easily or just didn't have the time to take off to go to town. I still miss going out to the truck every Saturday morning.
