I continue a tradition taught me by my Grandfather : I take my pennies and drop them randomly on the sidewalk in the town center. Sometimes I sit in my car and watch the delight on children's faces as they find the pennies and head for the penny candy in our local family-run Market!! Other times I drop and leave.
Sometimes an adult will spot a penny and pick it up and smile.

See a penny, pick it up,
All the day you'll have good luck.
OR
Find a penny, give it away,
Luck will follow you all the day.

Give it a try sometime when you have a few extra pennies!
