BDeserter -your comment about how to do maximum hours with minimum work is exactly how we used to do things!
I was in a congregation with a lot of rural territory. As soon as you left the KH and were walking down the High Street to the car you would do your damndest to get a tract in someone's hand! Start the time!
Then it would take approx 30 mins/45 mins to get to the car, and drive to the territory.
Then the clever thing is to make sure that you do the same in reverse - ie if your lived a long way from the territory you call on one of your neighbours when you get home. End of time!
We moved congregations from a town to a rural congregation, but didn't move house. We kept a short list of return visits from the town that we could use to start and end time.
Of course we only started doing this once we got wise to how everyone else was reporting so many hours! Before that we were actually honest about what we reported!!!
Crazy days!
