Hard to answer on the "real" first job, isn't it.
Well if we aren't counting walking beans(only done in when the beans are still small but weeds are big-pre weed killer days!) for my dad, babysitting, mowing lawns, picking apples at the local orchard, etc... I guess my first job (that Uncle Sam was involved) was working for So-Fro Fabrics. I think I got $2.35/hr & my girlfriend got a "raise" for getting me to work there because it made me low man on the totem pole, earning "student" wages. I think her raise was to $2.50/hr. And I must say I learned more at that job, about quirky people than any 16 year old should ever want to know! Once a fabriholic always a fabriholic! LOL!
