We notice it here in Cornwall, UK. Most of the time everyone is super friendly, lots of hellos and smiles between people you see in the street, even strangers.

Then it's holiday season and the place fills up with visitors - there's a palpable change in the interactions. I make a special effort to say HI and smile very enthusiastically during these times, see if I can break people out of their misery :-)
