in a big city with over a million people the jws had 4 or 5 trolleys going and they all had magazines printed in either 2021 or 2020.
why i think the watchtower is going for zero hours is so that they do not have to print as many magazines each time so saving money.because if you are going from door to door you are more likly to give out magazines or even single page tracts that they fold up (these days) but most people on the trolleys they just stand there by the trolley with nothing to hand. and if the numbers do go down in a country i dont think the corporation is really bothered esp if ut is in a western country where they can sell off the kingdom hall
