The blindfold walk

The task was to get a group of city planners to look at London with fresh eyes. 
So I split them into small groups and gave them a blindfolded tour guide. 
The tour guide had learned a route - but needed to be told where they were and what was there every step of the way. No space for being clever - just a real need to be specific and observant and clear.

No photos, so you have to imagine looking for a kerb. Waiting for the lights to change. Inviting people to look at the view from London Bridge without being able to see it. It's busy here. OK - the crowd is thinning out now. Is it left or right now? An underground travelator, City Hall, HMS Belfast, Tower Bridge...
