One summer during my college years, I took a job with The New York Central Railroad on a signal crew. We were mostly college kids and on our first day, we built up our sagging muscles by emptying out a gondola car of sand. The rest of the summer was spent digging deep holes for a line of telephone poles along a new switch-over connecting the Main Line to the North Shore Line. It was hard work in the hot, humid New York summer, but we were given enough breaks to replenish our water (and beer) supply.
One day, one of the gang brought a large basket of home grown cucumbers. On our break, we dug into the basket. I can still remember how cool they tasted and how refreshing they were. They certainly slaked our thirst. Today, the sight of a large green cucumber brings back the memory.
