I found BCP161 Edmonton.
I usually like to try to find the cap before I have to take out the metal detector. That changed at this one, it was almost 9:30 pm and when I walked to GZ a nearby dog decided to announce my presence. With the time of day, the dog and the fact that I was looking around just on the other side of the fence to some backyards, I decided to quickly grab my metal detector. Luckily I go a reading right away, snapped some pics and move on to the next one. Thanks for another cap in an interesting green space. TFTBC
