I have a few reactions to this story:
City Pages: Greenway cyclists ticketed by phantom cop...
Star Tribune: Not so fast, officer warns bikers
Mpls Bike Love Forum - Police ticketing bikers on Greenway
1) The speed limit isn't 10mph on the Greenway
2) "You'll never catch me!"
3) Who is this phantom police officer, which city do they work for, and why are they radar-ing bikers when they could be out catching bad guys?
Okay, now that I've got that out of my system...
Don't "run" from the police, even on a bike. They will find a way to catch you and it isn't worth it. If an officer waves you over, move over and stop. BE POLITE. Officers are trained to be in control of a situation, so let them do their job and both of you will be easier for it.
Until next time, ride long and keep the rubber-side down.
