And as usual people melt in the rain (second comment):
"They do realise we live in the North where rain and wind determine whether it's nice enough to walk? Walking on a nice summer's day is fine but try it when the gales are blowing."
I do wonder at all of these endless campaigns that basically just say to people "Hey, walking and cycling is really good for you, why not try it to get to work?" without any infrastructure as an incentive to do it, or restrictions on motor vehicles as a disincentive to use the, and realise the utter pointlessness of them. I wonder how many people are employed to come up with this and maintain the facade that things are changing?
