In the 1960s (1962, I believe), my new bride and I joined a group of young JWs who went to Utah during the early summer to Witness for a week in remote areas.
It was kind of cool, but uncomfortable as hell. The first couple of nights we camped out in one of the national parks (I think it was Zion). Some slept in the cars we came in, a couple had tents. My wife and I shared a big sleeping bag. We later had to move it to the top of a picnic table because there were rattlesnakes and other creepy crawlies that we had to beware of. We'd shower in the park's restrooms and then drive out of the park to some long forgotten small town with about 35 - 40 people. Witnessing was a waste of time, but we got a good education out of our trip.
In those days, many of the Mormon families lived in houses that were about 80% underground. It was weird walking up to a home that looked like it had just collapsed and walk "down the porch." I'm not sure about now, but in those days, underground houses were still quite common in the remote areas. (UC Davis financed and built several "green homes" in the same category in the Sacramento, California area in the 1970s and 80s.)
The Mormons were all very nice, but dealing with them was a lot like trying to preach to JWs. Their religion was also their culture and cult. Everyone up, down, and sideways in their family trees were Mormons. To even suggest that they consider another religion was out of the question. So they would end up preaching to us instead of us preaching to them.
Basically our 4-5 days in service were just part of an educational experience for all of us. It was exhausting in every sense of the word and totally fruitless. It was like going to Afghanistan and trying to preach to the Taliban. Most of us came home tired and sick. My kidneys were a mess because the water was so alkaline and there was no place to pee. I had strep throat and a 104 fever when we got back to Southern California. My wife had been on her period the whole time, so she was a mess and miserable.
Not fun. Not productive. Even now, I think most of the JWs are just in the larger cities like Salt Lake, Provo and Ogden where there are a lot of non-Mormon residents. But out in the country - not many. Living out there and being anything but a Mormon would make you outcasts.
