This is the Bonus Cache for the Ventura County Historical Monuments Adventure Lab. To get the Final Coordinates for this cache, you *must* complete the associated AL. While doing that Adventure Lab, you will be asked to enter numbers at each of the five stops. Not only will those numbers allow you to log a Find at each stop, they will be used to calculate the position of this Bonus Cache. So, then...
A = the answer to Bardsdale United Methodist Church - VCHL #50
B = the answer to Santa Clara Chapel Original Site - VC PoI #8
C = the answer to The Bard Memorial - VCHL #20
D = the answer to Chumash village of Sa'aqtik'oy - VC PoI #6
E = the answer to Timber School House and Auditorium - VCHL #166
This cache is located at N 34° 14.UVW' by W 119° 09.XYZ'
To determine the values of 'U' through 'Z', do the following steps:
'U' is the sum of the last two digits of D.
'V' is the first digit of E.
'W' is the sum of the two digits of A.
'X' is the sum of the second and fourth digits of E.
'Y' is the last digit of B minus twice the first digit of B.
'Z' is the second digit of C.
The checksum of U+V+W+X+Y+Z = 24.
You can also directly put your answer into the Solution Checker box, below; if it is correct, you will get a success message, and the coordinates for this cache will automatically update. The cache container is a diabetes test strip container, camoed to more-or-less match its placement. You should need no further Hints.
Good luck! Have fun 
Be safe.
