Short multi in Waterfront Park
Use the plaque at the coordinates to determine the missing characters. Enter what's missing into Certitude to receive coordinates to the second stage and a hide hint. Good luck!
This cache replaces GCB9455, which used first letters / initials of the words on the plaque to form a keyword. This one is similar, but has a slight twist. Solving that one first may help solve this second one.
