Here's a story about Calgary deciding to target cyclists on the city trail system for speeding tickets ($50 per ticket): http://www.cbc.ca/canada/calgary/sto...socialcomments

As a cyclist on these trails I am dismayed by this situation. I ride on these trails for exercise purposes, and always with courtesy for other trail users. Now if I go faster than 20kmph(!!) I may be coming home with a speeding ticket.

I'm interested to see if anyone out there has encountered a similar situation in their own cities, and what, if anything, was done about it by the cycling community.
