Tweetie, I'm old. I can remember field service starting at 9 am, afternoon sessions at 1, evening sessions around 6 lasting until 9. If you count traveling time to and from each day and meal breaks breakfast, lunch and dinner, it could be 12 to 14 hours that you were on the assembly grounds. And some of these lasted 8 days. Can you imagine the cost to a family and the vacation time needed to go? In those days, JWs canvassed the neighborhood for rooms to rent from householders which was meant to hold down the costs. Some JW families were bad and stole from their "hosts."
