I've seen a few around Leeds but I was startled to see some in Truro last year while on holiday. Three on benches outside Cathedral and one on grassed area opposite the 60s multi-storey car park. I couldn't have imagined it in a relatively affluent (or so I thought) location.
They might of been drawn to the area because of it's wealth. Churches and other such places usually you see many of them around them. Maybe homeless people feel safe around them.
Yup, that does make sense.
It's so sad that with just a little knowledge, these folks could have better control over their destiny. Education(or perhaps indoctrination) has made us all believe that we have to be completely reliant on the authorities for our existence.
