I am in an area where 98% of people are hispanic and over 60% speak spanish at home. South Texas, near Brownsville. Here we were instructed, starting about a year ago, to make sure (as per the CO) that no territory would be turned back in without a not-at-home that has not been catch at home at some point. Gives the pioneers lots to do. Otherwise, the area each cong has is too small for any one pioneer to work on. They have put a lot of weight on that mandate. Every house needs to be visited before turning it in. The territory map and the notes are turned in at the end of the month so that the elders can make a report but you can have it right back to continue working it.
Ironically, we also have been instructed to refrain from entering properties with a "keep-out" sign or even if the gate to the property is open. Some time ago, a couple of sister went into a large house with an automatic gate. Even when the saw the owner had just left, the message is so urgent, that they had to go in, hoping someone would be left at home. In between walking and and knocking, the gate closed by itself, locking the sisters inside the yard. You can imagine the mood of the owner when he was somehow located and asked to return and free the children of God.
So last time i went in service, 6 months ago, it was like walking the streets for relaxation. We just walked by hoping to find someone cutting the grass. Otherwise, most houses has closed gates and fences. We had no other recourse but to grab a rock and bang it against the hurricane fences, in the hopes that we would caught someones attention.
