... so, you nip across the road on the crossing, no traffic, and look up to see four long sets of steps going up to the station... what's that odd shaped bit of kerb doing there... I want to walk right across it! I want to get climbing straight away, all in one breath, to the top.
Do pairs of people do it side-by-side? Is it someone and a bicycle? Do people go one way and come back the other? What will happen to the tufts of grass in the middle? Which path did I take today?
