The Traditional Bowhunters of Washington hold a mid-season 3-D event every October with a similar theme. We set out 3 courses of 15 animals each...but no shooting stakes. Archers walk the trail, finding the critters and shooting from first view.
It's more fun to rotate lead shooters if groups go out...and some targets are designated as broadhead targets.
It's lots of fun, generating discussion
about which target they did or did not see.
Scoring is optional, but having a good time is mandatory.
