Hopping in the airport? You are a brave man! I don't think I'm brave enough for that.As for stealth I've definitely hopped at Penn Station, and often in the airport, it can't get stealthier.
I have used the hopper in a movie theater during the movie. I used a smoke buddy jr. to get rid of visible vapor and odor. It worked like a charm. I've also hit it directly in front of a police station while passing by.
