I think its more of a case that people lack the confidence to just approach a group and introduce themselves. I know i do, its no crime. Its just how i am.
I did recognise alot of cars, i saw yours just before we were about to leave Dohmar, but no-one was next to the car, otherwise i would have come introduced myself. Next time, ill bring my "Hello my name is stickers" to make it easier for everyone
