Back in the day when I was a zealous pioneer there used to be a group of us pioneers who would go on the college campus to do street work. There would be large groups of students who would all walk together and if you could get one student to take a mag then every student following them would take one. Some days I would literally place 300 to 500 magazines. The really funny thing was that after a group of 50 or 100 students would walk by then there would be a lull in the action. No students would walk by for a while. So we would walk down to the bottom of the hill and check the trash cans to see how many of the mags we had just placed had already made it into the barrel. Sure enough there would always be at least a 1 to 5 ratio of discarded magazines. So we would take them back out of the garbage and then when the next group of students would go by we would place those same mags again. (As long as they hadn't been soiled by anything in the garbage.) And of course that meant I sometimes got to count 2 placements with the exact same magazine. My all time record, 681 magazines in one day. And it wasn't hard to come up with that many magazines. I was also the "magazine servant" at the time so I had an announcement made that any publisher who had magazines at home that they felt they wouldn't place could bring them up to the magazine counter and we would be glad to see to it that they got redistributed to other publishers who were in need. We literally got thousands of magazines (between 3 and 4 thousand if I recall correctly.) Now that is just one congregation of about 80 publishers, multiply that by 90,000 congos and you know there are a lot of old mags out there that never get placed.
