I love the "welcome home" from
Passport control here in the US, I think it's amazing.
Logan immigration has been very friendly to me in the past.
These days I'm not in Boston and usually come in through Newark Liberty. Half the time I get a nice friendly/chitchatty immigration officer who welcomes me back.
Nowadays most airports do that electronic thing, so they don't even need to ask you questions since its all on that slip of paper. So a couple of times I've had them glance at the slip, and then just welcome me back with a smile.
