I heard this term used a while ago too. I think quite a few latched onto the term. I just thought "damn that's pretty creative".
Too many in western lands are hitting the wall as far as the 'field service' goes. It's like they know they are just driving around, hitting the coffee and doughnut shops just putting in time.
About the only people that do come into the 'truth' these days in this part of the world are basically society's left-overs, therefore "gleaning" seems an appropriate term.
