Signs, Omens, and Portents in Nebraska Folklore
I love the list of weather portents that starts on pg 11 of the book (or pg 9 of 48 in the pdf document pagination)
#23. When a snake is killed and hung up, it will rain. the higher the snake is hung, the harder it will rain.
Portent's of love
#14. If your shoe string comes untied, your sweetheart is thinking of you.
#20. If a girl takes the last piece of bread or cake from the plate, her marriage will be postponed seven years.
