I think this is a touching and very moving story. Even were it 100 untrue, it would still be a beautiful post. Maybe I am naive, but I believe it to be true, and the people in the story recounted, were clearly doing Tashlich. They might even have been Chabad, who are known to go ANYWHERE and EVERYWHERE.
Aurora, whoever you are, if this story is exactly as you described it, then it seems clear that Hashem is tapping you on the shoulder and saying, as it were, “Go for it! I’m sending you some help.” Little steps can bring you on great journeys.
