While we're talking about Mexico, I've heard about a weird phenomenon. It's become quite the thing for Canadian JWs to spend time in Mexico as "need-greaters" in the English congs, esp. in resort areas--but in other less-touristy areas as well. From what I've heard from family members who have done this, they comb a neighborhood for anyone who speaks English, even if it's a native Mexican who can barely utter a few words. The Hall is filled with either Canadian ex-pats or locals who speak anywhere from badly broken to manageable English.
Seems to me like a colossal waste of time (even more so than regular field service). In their home cong., these same JWs would be encouraging non-native English speakers to attend a cong or group in their mother tongue, would pass the call on to someone fluent in that lang., etc. Down there, by contrast, they waste hours and hours of time trying to find ANYONE who can speak Engl and then get them to come to an English KH where they might understand a tiny fraction of what is said. Is it just me or is that plain weird? Then, in the summer, the snowbirds go home and the cong. shrinks to a quarter of the size.
And yes, there doesn't seem to be the ban on higher ed down there either--my family member was bragging that there are teachers and attorneys in the cong who are also pioneers!!!
