Hunter & Grace Visit Morgan Run NEA: 9 Mystery Cache

​My young friends Hunter and Grace (and, yes, their mom JAB430) helped me place the hides in this series.  We all hope you find the actual hides interesting and challenging.  As for the puzzles, they are in honor of my niece Georgea, who has had to solve these little math problems in her third-grade curriculum in Arizona.  So, are you at least as smart as a third-grader?

Georgea had a total of 20 California quail and jackrabbits--odd pets, I know, but Georgea is a most interesting child!  The animals, she told me last visit, had 56 legs.  Thinking she could stump me, she asked how many quail and how many rabbits she had.  After a little arithmetic, I decided to tease her a tad.  I told her that if she added 12 times the number of quail legs to the last 3 digits of the given north coordinates, and 12 times the number of jackrabbit legs to the given west coordinates, she'd be able to find this cache.
