I know what you mean journey-on:
That feeling of community is hard to live without. Just occasionally if I drive past a bunch of Witnesses on a street corner I feel a tiny stab of nostalgia (until I slap myself in the face and drive on . It's definitely not the Witnessing I miss, ...but the relaxed stroll around the street with a friend having a good chat, believing that you are doing a good thing.
But anyway, thats not to say that good friends can't be found elsewhere, right?
