This memory is compliments of my Mother
When we moved into our new house, the front of the house was landscaped using railroad ties as borders for the shrubbery. Shortly after we moved in, Mum planted tulips out front and one spring something ate the buds off the tulip stalks before they ever had a chance to bloom? She thought there might be a little varmint of some kind that was biting them off so Dad decided to flip over a railroad tie and there was a little cache of the missing tulip buds! They were not sure what did that but suspected it was a mole. They speculated that it could have been a chipmunk but they had never seen one around.
It will always be an unsolved mystery.
