This is why I was wondering if the old way of checking out territories, working the doors (to death) and keeping all the records had gone away. I'm aware from reading other threads that keeping "not at home" records may not be compliant with new privacy laws in the UK, and of course the US could follow that path.
I don't hear any conversation these days about checking out territories and keeping up on return visits. The "zeal" just doesn't seem to be there. But then, the ones I still know are so busy trying to make a living there's not a lot of extra time. Door to door might just die out due to lack of enthusiasm. I don't even see the local Mormons going around town.
