Some Jewish people perform the tashlikh. This is the custom of reciting prayers near naturally flowing water, such as a stream or river, and symbolically throwing one’s sins away in the form of small pieces of bread or other food. Many Jewish people perform tashlikh from places such as the Brooklyn and Manhattan bridges in New York. Some people may use a fish pond or mikveh (ritual bath) if there is no local river or stream.
I seem to have a recollection of same. So there you are!
