Calgary, Alberta Speed Traps
Shaganappi Street near Top of Nose Hill Park
They sit at the top of the big Shaganappi Hill (on right side coming up hill from John Laurie) with their Lasar on a tripod behind the concrete barrier. Most people are slow in the left lanes turning into Edgemont so the fast line is on the right. No houses and several open kilometers of 3 lane road makes this 80 km limit too slow.
Memorial Dr NE between 44St & 52St
Just for last month I saw van or truck with photo radar 4-5 times. Speed limit 50, I got ticket for 65. Amount of cops increasing every day 
Memorial Trail near East 52nd Street
Usually a red or a silver minivan with a photo radar on the westbound or eastbound Memorial Drive before intersection with 52nd street SE.
Acadia Drive and Willigdon Blvd.
As vehicles are coming Southbound on their way home from work on Acadia Drive thru Willow Park and Mapleridge, just as you pass in-between the two golf courses, they sit on the corner beside the bus stop on the West side (your right). They are there on the odd week-end, but mainly evening rush hour. HOWEVER, lately, during the same time, I have seen them across the street in this same area nabbing drivers going Northbound! LOOK OUT!
Bow Bottom Trail near 137 SE Avenue
Police vehicles often park in the driveway of the Church just before 137th Avenue checking vehicles traveling north on Bow Bottom. They are obscured from view by a fence.
