For us it was working our German Grandma's grape vineyard in the central valley Fresno area during the summers, fall and winter. Summer it was hand weeding half of the 60 acres of grapes(grown for raisins) in high heat, Fall was harvest season running behind tractor picking up paper drying trays of raisins out of the fields and throwing them into a collector bin, then in winter when everything was dormant and the temps were in the 30's -40's cutting canes and tying them to wire rails. It built character, and the desire not to be doing this when I was older(great incentive for school work). Grandma was the best boss, she was a task master and let you know if you were skipping a weed, etc... :)
