My parents used to love to go fishing. They took us along on many fishing trips, and in later years, took their grandchildren fishing, too. We didn't really care what we caught - we loved the adventures and the excitement of having a little fishy tugging on the line!
To get the coordinates to the final cache, look at the statue of children fishing at ground zero.
The coordinates to the final are:
N 43 20.ABC W 092 08. DEF
A = the number of letters in the artist's last name (etched on top of the log)
B = the number of white shells and snails
C = the number of 'K's in Charles' last name
D = the number of fishing boats
E = the number of 'E's in Charles’ wife’s first and last names combined
F = the number of letters in Amy's last name
