Thanks again to everyone! I've found some bags on Amazon and ebags that I'm going to consider.
I don't like a "huge" bag. I want to put $$, credit cards, a scarf (for visiting synagogues or churches), some tissues, a camera and a water bottle in a bag.
I don't want a waist bag, I think they're uncomfortable and "shout" tourist
! I will probably keep the majority of my $$ and credit cards in a neck safe.
