The cache is not at the posted coordinates. Instead, you will find a monument to a congregation consisting of members from both Charlotte and Washington Counties. To locate the cache, solve the following puzzle:
N 45 AB.CDE W 067 FG.HIJ
ABCD = Year that the synagogue was erected, minus 809.
E = Numerical value of the month the monument was erected, plus one.
FG = Years the synagogue was in existence, minus 47.
H = Last number in the date of dismantling of the building.
I = Also the last number in the date of dismantling of the building.
J = Number of dates, in years, described in the third line of the inscription.
Good luck and enjoy the hunt!
