One of the favorite escapes for the downtown lunch crowd is Princes Island Park (PIP). This puzzle cache will show you around the park. The posted coordinates will take you into the park. There is a bench with a memorial plaque for Yu, Ming. There are two dates on the plaque.
First date - ABCD.E
Second date - FGHI.JK
Coords - N 51 G(A+E).F(I-J)I W 114 GI,(D-E)K(C-F)
(FYI ... the puzzle has been changed, but the final is the same.)
