You've been Ducked!
"Duck Duck Jeep" refers to the trend of Jeep owners placing rubber ducks on other Jeep vehicles as a form of friendly recognition or appreciation. It started with Allison Parliament, who placed a rubber duck on another Jeep with a note, igniting a community-wide random act of kindness. Now there are rubber ducks everywhere!
This cache is located at the beginning of a Jeep trail. No 4x4 is necessary. No bushwhacking is involved. Pretty much a park-n-grab. Good luck and happy hunting!
