A one foot long piece of 2x4 with a nail in it that the point sticks through a quarter of an inch. Bury them about six inches apart and four and a
half inches deep. Before burying them, set them in your holes, and take a two and three quarter inch piece of one inch pvc and center it on the nails.
Fill in the dirt around the pvc and VERY carefully set a two and three quarter inch 12ga shell in each one. Cover with leaves and don't forget where
you buried them
