Is this where we tell our extreme turbulence stories?

A long time ago in another life...I was flying YYC-YUL on CP. It was a CP flight and I seem to recollect that it was a B767. We were at cruising altitude somewhere over the prairies and the FA was serving drinks from the trolley. We hit clear air turbulence and the aircraft dropped. I remember the trolley spilling its contents in the aisle and the FA falling into the middle row (empty seats)
No one was hurt except probably some bruising. The first officer came back late for a visual of the wings .

How far did we drop? I have no idea. I just was happy to have my seatbelt on!
