Overheard two motorcycle cops just now, talking about Highway 71. Apparently there was a police meeting somewhere at that moment discussing crackdowns on speeders on on 71. As one put it, "5 mph over can happen without you knowing it, but 10 - you're speeding on purpose. I might give a warning." The other said, "if 10 over, and on the phone, it's a ticket for them."
Be warned. And safe.
