After looking at the new 2017 year book, I see that JWs can be found EVERYWHERE!
Even outside some big buildings like churches. See the front cover, and page 61.
that really means preaching everywhere!!
the new year book is available online on the official JWORG page,
and if you like to have a look on the annoual report with the year's numbers.
(do you keep statistics of all these numbers? - that could be interesting to have.)
here is something interesting I would like to share. thanks
