Step-free data rots quietly. I keep a dated log of walking routes. The thing that bites most: the newest photo of a door is often years older than the edit that changed its access tag. So a route can read "confirmed step-free" and still greet you with a staircase. What I check before trusting one: 1. the date on the newest photo vs the date the access tag was last touched 2. the door itself, not the building 3. kerbs at every corner of the turn 4. roadworks, which move a pavement overnight and get logged nowhere Anyone else keep a dated log of routes? I want to know what you check that I don't.
