People must have been more agile when the houses were built in Susan Street, Annandale, in the 1800s.

Arncliffe’s favourite staircase is at 16 Segenhoe Street. It was made when Alan was aged minus five, and originally had pride of place in an old Parramatta hotel.

A high rise in Waterview Street, Balmain.

These are just a few of the 558 steps Alan covered in his 90-minute walk this day. On this site, now Hopetoun Quays, was once the deepest coal mine ever sunk in Australia. See its remains and the new buildings at the eastern end of Gow Street, Birchgrove.

Motorists planning their route through Cammeray with the aid of their street directory are in for a surprise when they attempt to drive down Johnston Avenue.
