Like many others, I cut across Palmerston Place in the morning, cycle alongside the cathedral and (like slightly fewer others) *may* have been known to turn left and go the not-entirely-correct direction up the one-way Manor Place and turn right into Melville Street.
Not today, though. Three policefolks stood on Manor Place, stopping cyclists who are on the pavement or are going the wrong way up the one-way street.
Can't fault their legal point of view, but it does seem a bit OTT, resource-wise.
Be aware, all, that there does seem to be a crackdown on ensuring that cyclists are adhering to the rules.
