This is a simple two stage Mystery Cache that I hope even traditionalists can enjoy. It is kid friendly, though there is some light bushwhacking at the final. The Theme is Heroes, and the final is a large box with trading items that are heroes of some sort, they can be Superheroes, movie heroes, military heroes, your hero, etc. Please bring a hero to trade and keep the theme alive.
At the above coordinates you will find a Vietnam Veteran Memorial. On the plaque on the large stone there are 3 dates and a number of trees.
1) Find the digital root of each date using the concept of additive persistence.
2) Consider the the three numbers or digital roots, disregard the Prime Number and the Perfect Square. Call the remaining number "V".
3) There are a number of trees mentioned on the plaque. Find the digital root of this number and call it "N".
Final is located at these coordinates:
