The cache contains a log only so BYOP. Be stealthy at GZ. The posted coordinates bring you to a park and walking trail. There is a pond next to the trail that currently has ducks.
At the posted coordinates you will find a sign with a by-law number on it. Take the last 3 digits in this number and divide them by 1000. Add your result to N 43 9.394 and W 79 28.128 . Apologizes ahead of time to Romel if I screwed this one up.
