In reply to Ava Adore:
It's nearly 4 miles from Kingston station. If you got out at the station and thought you might walk (which would be reasonable), and then managed to find the right people to ask the way, it would still take you about an hour to get there.
An hour the other direction and you'd be in central london.
I was really pleased there's a new wall in my area, just a bit pissed off that it's not actually in my area.
