Found BCP575 McDougall United Church.
When I parked for this cap I noticed a vehicle coming up to the stop sign across the highway. Even though I had my back turned I knew that they hadn't moved after stopping. After taking the photos and leaving I kept checking the mirror but they never moved even after I left. I thought that was a little odd. Nice to see a cap that lets people know the punishment for removing it as it is stamped right on the top. Another unique location with a can't miss cap. TFTBC
