I'm generally in favour of cycling - it's a great way to exercise and a good way to cut down on carbon emissions - but I've seen some pretty stupid bicycle riders in my time. Today three guys on bikes not only entered the tunnel under the inner-northern Normanby Fiveways against a sign that clearly indicated they were not to do so, they also wandered all over the road. Nobody deserves to get hurt, but these guys were really pushing their luck and it would be hard to blame any motorist who might have accidentally hit them.
