Glad you found the joy and practice value of stump shooting!
When I started shooting a bow with a childhood friend at around 9 years old, we did as much stump shooting as anything else. Living in the country, we'd pack a lunch and spend all day in the woods roaming the local farmlands.
Geez...I wonder how many kids get to do that anymore! We probably ate lead paint too! :-)
Anyway, been stump shooting ever since. Other than actually hunting, it's my favorite thing to do with a traditional bow in hand.
