Someone told me that the 1000 steps walk over in the Dandenong Ranges was originally built as a downhill MTB trail but then the walkers discovered it and got upset at the MTBers using it - 'This is a walking trail' 'No it's not' - and then it became a sanctioned walking track with loads of stairs. We're fighting a losing battle!
:(
Totally built berms for walking!
Obviously it was for water runoff!
